the owner of all installed files is a non-root user. This change
affects most packages that require special users or groups by making
them use the specified unprivileged user and group instead.
(1) Add two new variables PKG_GROUPS_VARS and PKG_USERS_VARS to
unprivileged.mk. These two variables are lists of other bmake
variables that define package-specific users and groups. Packages
that have user-settable variables for users and groups, e.g. apache
and APACHE_{USER,GROUP}, courier-mta and COURIER_{USER,GROUP},
etc., should list these variables in PKG_USERS_VARS and PKG_GROUPS_VARS
so that unprivileged.mk can know to set them to ${UNPRIVILEGED_USER}
and ${UNPRIVILEGED_GROUP}.
(2) Modify packages to use PKG_GROUPS_VARS and PKG_USERS_VARS.

Prompted by report from Peter Avalos that exim 4.66 would not build
against openssl 0.9.8e
Changelog:
MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
is unset (happens when testing with -bh and -oMi isn't used). Thanks to
Jan Srzednicki.
PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
issue a MAIL command.
PH/02 In an ACL statement such as
deny dnslists = X!=127.0.0.2 : X=127.0.0.2
if a client was not listed at all, or was listed with a value other than
127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
the condition was not true (as it should be), so access was not denied.
The bug was that the ! inversion was incorrectly passed on to the second
item. This has been fixed.
PH/03 Added additional dnslists conditions == and =& which are different from
= and & when the dns lookup returns more than one IP address.
PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
cipher suites used by GnuTLS. These options are ignored by OpenSSL.
PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
FSYNC, which compiles an option called disable_fsync that allows for
bypassing fsync(). The documentation is heavily laced with warnings.
SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket.
PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
including adding "make clean"; (3) Added -fPIC when compiling the test
dynamically loaded module, to get rid of a warning.
MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
message fails, move_frozen_messages = true and ignore_bounce_errors_after
= 0s. The bug is otherwise harmless.
PH/07 There was a bug in the dovecot authenticator such that the value of
$auth1 could be overwritten, and so not correctly preserved, after a
successful authentication. This usually meant that the value preserved by
the server_setid option was incorrect.
PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.
PH/09 Installed PCRE release 7.0.
PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
run for batched SMTP input. It is now run at the start of every message
in the batch. While fixing this I discovered that the process information
(output by running exiwhat) was not always getting set for -bs and -bS
input. This is fixed, and it now also says "batched" for BSMTP.
PH/11 Added control=no_pipelining.
PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
patch, slightly modified), and move the expansion of helo_data till after
the connection is made in the smtp transport (so it can use these
values).
PH/13 Added ${rfc2047d: to decoded RFC 2047 strings.
PH/14 Added log_selector = +pid.
PH/15 Flush SMTP output before delaying, unless control=no_delay_flush is set.
PH/16 Add ${if forany and ${if forall.
PH/17 Added dsn_from option to vary the From: line in DSNs.
PH/18 Flush SMTP output before performing a callout, unless control =
no_callout_flush is set.
PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
was true (the default) a successful delivery failed to delete the retry
item, thus causing premature timeout of the address. The bug is now
fixed.
PH/20 Added hosts_avoid_pipelining to the smtp transport.
PH/21 Long custom messages for fakedefer and fakereject are now split up
into multiline reponses in the same way that messages for "deny" and
other ACL rejections are.
PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
with slight modification.
PH/23 Applied sieve patches from the maintainer "tracking the latest notify
draft, changing the syntax and factoring some duplicate code".
PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
for deliveries of the second and subsequent messages over the same SMTP
connection.
PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
${reduce, with only minor "tidies".
SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
expansion side effects.
PH/27 When a message times out after an over-quota error from an Exim-imposed
quota, the bounce message says "mailbox is full". This message was not
being given when it was a system quota that was exceeded. It now should
be the same.
MH/03 Made $recipients available in local_scan(). local_scan() already has
better access to the recipient list through recipients_list[], but
$recipients can be useful in postmaster-provided expansion strings.
PH/28 The $smtp_command and $smtp_command_argument variables were not correct
in the case of a MAIL command with additional options following the
address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
were accidentally chopped off.
PH/29 SMTP synchronization checks are implemented when a command is read -
there is a check that no more input is waiting when there shouldn't be
any. However, for some commands, a delay in an ACL can mean that it is
some time before the response is written. In this time, more input might
arrive, invalidly. So now there are extra checks after an ACL has run for
HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
pipelining has not been advertised.
PH/30 MH's patch to allow iscntrl() characters to be list separators.
PH/31 Unlike :fail:, a custom message specified with :defer: was not being
returned in the SMTP response when smtp_return_error_details was false.
This has been fixed.
PH/32 Change the Dovecot authenticator to use read() and write() on the socket
instead of the C I/O that was originally supplied, because problems were
reported on Solaris.
PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
Exim which did not show up earlier: it was assuming that a call to
SSL_CTX_set_info_callback() might give an error value. In fact, there is
no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
was a macro that became an assignment, so it seemed to work. This has
changed to a proper function call with a void return, hence the compile
error. Exim's code has been fixed.
PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
cpus.
PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".
PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
PH/37 If a message is not accepted after it has had an id assigned (e.g.
because it turns out to be too big or there is a timeout) there is no
"Completed" line in the log. When some messages of this type were
selected by exigrep, they were listed as "not completed". Others were
picked up by some special patterns. I have improved the selection
criteria to be more general.
PH/38 The host_find_failed option in the manualroute router can now be set
to "ignore", to completely ignore a host whose IP address cannot be
found. If all hosts are ignored, the behaviour is controlled by the new
host_all_ignored option.
PH/39 In a list of hosts for manualroute, if one item (either because of multi-
homing or because of multiple MX records with /mx) generated more than
one IP address, and the following item turned out to be the local host,
all the secondary addresses of the first item were incorrectly removed
from the list, along with the local host and any following hosts (which
is what is supposed to happen).
PH/40 When Exim receives a message, it writes the login name, uid, and gid of
whoever called Exim into the -H file. In the case of the daemon it was
behaving confusingly. When first started, it used values for whoever
started the daemon, but after a SIGHUP it used the Exim user (because it
calls itself on a restart). I have changed the code so that it now always
uses the Exim user.
PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
message are rejected with the same error (e.g. no authentication or bad
sender address), and a DATA command is nevertheless sent (as can happen
with PIPELINING or a stupid MUA), the error message that was given to the
RCPT commands is included in the rejection of the DATA command. This is
intended to be helpful for MUAs that show only the final error to their
users.
PH/42 Another patch from the Sieve maintainer.
SC/02 Eximstats - Differentiate between permanent and temporary rejects.
Eximstats - Fixed some broken HTML links and added missing column headers
(Jez Hancock).
Eximstats - Fixed Grand Total Summary Domains, Edomains, and Email
columns for Rejects, Temp Rejects, Ham, and Spam rows.
SC/03 Eximstats - V1.58 Fix to get <> and blackhole to show in edomain tables.
PH/43 Yet another patch from the Sieve maintainer.
PH/44 I found a way to check for a TCP/IP connection going away before sending
the response to the final '.' that terminates a message, but only in the
case where the client has not sent further data following the '.'
(unfortunately, this is allowed). However, in many cases there won't be
any further data because there won't be any more messages to send. A call
to select() can be used: if it shows that the input is "ready", there is
either input waiting, or the socket has been closed. An attempt to read
the next input character can distinguish the two cases. Previously, Exim
would have sent an OK response which the client would never have see.
This could lead to message repetition. This fix should cure that, at
least in a lot of common cases.
PH/45 Do not advertise STARTTLS in response to HELP unless it would be
advertised in response to EHLO.

Exim version 4.66
-----------------
PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
fixed by 4.65/MH/01 (is this a record?) are fixed:
(i) An empty string was always treated as zero by the numeric comparison
operators. This behaviour has been restored.
(ii) It is documented that the numeric comparison operators always treat
their arguments as decimal numbers. This was broken in that numbers
starting with 0 were being interpreted as octal.
While fixing these problems I realized that there was another issue that
hadn't been noticed. Values of message_size_limit (both the global option
and the transport option) were treated as octal if they started with 0.
The documentation was vague. These values are now always treated as
decimal, and I will make that clear in the documentation.
Exim version 4.65
-----------------
TK/01 Disable default definition of HAVE_LINUX_SENDFILE. Clashes with
Linux large file support (_FILE_OFFSET_BITS=64) on older glibc
versions. (#438)
MH/01 Don't check that the operands of numeric comparison operators are
integers when their expansion is in "skipping" mode (fixes bug
introduced by 4.64-PH/07).
PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
child addresses, Exim now panics and dies. Previously, because the count
is held in a short int, deliveries were likely to be lost. As such a
large number of recipients for a single message is ridiculous
(performance will be very, very poor), I have chosen to impose a limit
rather than extend the field.
Exim version 4.64
-----------------
TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
leftover -K file (the existence of which was triggered by #402).
While we were at it, introduced process PID as part of the -K
filename. This should rule out race conditions when creating
these files.
TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
processing considerably. Previous code took too long for large mails,
triggering a timeout which in turn triggers #401.
TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
in the DK code in transports.c. sendfile() is not really portable,
hence the _LINUX specificness.
TF/01 In the add_headers option to the mail command in an Exim filter,
there was a bug that Exim would claim a syntax error in any
header after the first one which had an odd number of characters
in the field name.
PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
callout verification, Exim cached a "reject" for the entire domain. This
is correct for most verifications, but it is not correct for a recipient
verification with use_sender or use_postmaster set, because in that case
the callout does not use MAIL FROM:<>. Exim now distinguishes the special
case of MAIL FROM:<> rejection from other early rejections (e.g.
rejection of HELO). When verifying a recipient using a non-null MAIL
address, the cache is ignored if it shows MAIL FROM:<> rejection.
Whatever the result of the callout, the value of the domain cache is
left unchanged (for any other kind of callout, getting as far as trying
RCPT means that the domain itself is ok).
PH/02 Tidied a number of unused variable and signed/unsigned warnings that
gcc 4.1.1 threw up.
PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
manifest itself as EPIPE rather than ECONNECT. When tidying away a
session, the daemon ignores ECONNECT errors and logs others; it now
ignores EPIPE as well.
PH/04 Applied Nico Erfurth's refactoring patch to tidy up mime.c
(quoted-printable decoding).
PH/05 Applied Nico Erfurth's refactoring patch to tidy up spool_mbox.c, and
later the small subsequent patch to fix an introduced bug.
PH/06 Installed the latest Cygwin Makefile from the Cygwin maintainer.
PH/07 There was no check for overflow in expansions such as ${if >{1}{4096M}}.
PH/08 An error is now given if message_size_limit is specified negative.
PH/09 Applied and tidied up Jakob Hirsch's patch for allowing ACL variables
to be given (somewhat) arbitrary names.
JJ/01 exipick 20060919.0, allow for arbitrary acl_ variables introduced
in 4.64-PH/09.
JJ/02 exipick 20060919.0, --show-vars args can now be regular expressions,
miscellaneous code fixes
PH/10 Added the log_reject_target ACL modifier to specify where to log
rejections.
PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
hostname. This is wrong, because it relates to the incoming message (and
probably the interface on which it is arriving) and not to the outgoing
callout (which could be using a different interface). This has been
changed to use the value of the helo_data option from the smtp transport
instead - this is what is used when a message is actually being sent. If
there is no remote transport (possible with a router that sets up host
addresses), $smtp_active_hostname is used.
PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
tweaks were necessary in order to get it to work (see also 21 below):
(a) The code assumed that strncpy() returns a negative number on buffer
overflow, which isn't the case. Replaced with Exim's string_format()
function.
(b) There were several signed/unsigned issues. I just did the minimum
hacking in of casts. There is scope for a larger refactoring.
(c) The code used strcasecmp() which is not a standard C function.
Replaced with Exim's strcmpic() function.
(d) The code set only $1; it now sets $auth1 as well.
(e) A simple test gave the error "authentication client didn't specify
service in request". It would seem that Dovecot has changed its
interface. Fortunately there's a specification; I followed it and
changed what the client sends and it appears to be working now.
PH/13 Added $message_headers_raw to provide the headers without RFC 2047
decoding.
PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
address A is aliased to B and C, where B exists and C does not. Without
-v the output is "A verified" because verification stops after a
successful redirection if more than one address is generated. However,
with -v the child addresses are also verified. Exim was outputting "A
failed to verify" and then showing the successful verification for C,
with its parentage. It now outputs "B failed to verify", showing B's
parentage before showing the successful verification of C.
PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
look up a TXT record in a specific list after matching in a combined
list.
PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
they consult the DNS. I had assumed they would set it the way they
wanted; and indeed my experiments on Linux seem to show that in some
cases they do (I could influence IPv6 lookups but not IPv4 lookups).
To be on the safe side, however, I have now made the interface to
host_find_byname() similar to host_find_bydns(), with an argument
containing the DNS resolver options. The host_find_byname() function now
sets these options at its start, just as host_find_bydns() does. The smtp
transport options dns_qualify_single and dns_search_parents are passed to
host_find_byname() when gethostbyname=TRUE in this transport. Other uses
of host_find_byname() use the default settings of RES_DEFNAMES
(qualify_single) but not RES_DNSRCH (search_parents).
PH/17 Applied (a modified version of) Nico Erfurth's patch to make
spool_read_header() do less string testing, by means of a preliminary
switch on the second character of optional "-foo" lines. (This is
overdue, caused by the large number of possibilities that now exist.
Originally there were few.) While I was there, I also converted the
str(n)cmp tests so they don't re-test the leading "-" and the first
character, in the hope this might squeeze out yet more improvement.
PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
flag allowing group syntax was set by the header_syntax check but not
turned off, possible causing trouble later; (2) The flag was not being
set at all for the header_verify test, causing "group"-style headers to
be rejected. I have now set it in this case, and also caused header_
verify to ignore an empty address taken from a group. While doing this, I
came across some other cases where the code for allowing group syntax
while scanning a header line wasn't quite right (mostly, not resetting
the flag correctly in the right place). These bugs could have caused
trouble for malformed header lines. I hope it is now all correct.
PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
with the "reply" argument non-NULL. The code, however (which originally
came from elsewhere) had *some* tests for NULL when it wrote to *reply,
but it didn't always do it. This confused somebody who was copying the
code for some other use. I have removed all the tests.
PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
feature that was used to support insecure browsers during the U.S. crypto
embargo. It requires special client support, and Exim is probably the
only MTA that supported it -- and would never use it because real RSA is
always available. This code has been removed, because it had the bad
effect of slowing Exim down by computing (never used) parameters for the
RSA_EXPORT functionality.
PH/21 On the advice of Timo Sirainen, added a check to the dovecot
authenticator to fail if there's a tab character in the incoming data
(there should never be unless someone is messing about, as it's supposed
to be base64-encoded). Also added, on Timo's advice, the "secured" option
if the connection is using TLS or if the remote IP is the same as the
local IP, and the "valid-client-cert option" if a client certificate has
been verified.
PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
authenticators. This can be used for authorization after authentication
succeeds. (In the case of plaintext, it servers for both authentication
and authorization.)
PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
if any retry times were supplied.
PH/24 Exim crashed if verify=helo was activated during an incoming -bs
connection, where there is no client IP address to check. In this
situation, the verify now always succeeds.
PH/25 Applied John Jetmore's -Mset patch.
PH/26 Added -bem to be like -Mset, but loading a message from a file.
PH/27 In a string expansion for a processed (not raw) header when multiple
headers of the same name were present, leading whitespace was being
removed from all of them, but trailing whitespace was being removed only
from the last one. Now trailing whitespace is removed from each header
before concatenation. Completely empty headers in a concatenation (as
before) are ignored.
PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
PH/29 [Removed. This was a change that I later backed out, and forgot to
correct the ChangeLog entry (that I had efficiently created) before
committing the later change.]
PH/30 Exim was sometimes attempting to deliver messages that had suffered
address errors (4xx response to RCPT) over the same connection as other
messages routed to the same hosts. Such deliveries are always "forced",
so retry times are not inspected. This resulted in far too many retries
for the affected addresses. The effect occurred only when there were more
hosts than the hosts_max_try setting in the smtp transport when it had
the 4xx errors. Those hosts that it had tried were not added to the list
of hosts for which the message was waiting, so if all were tried, there
was no problem. Two fixes have been applied:
(i) If there are any address or message errors in an SMTP delivery, none
of the hosts (tried or untried) are now added to the list of hosts
for which the message is waiting, so the message should not be a
candidate for sending over the same connection that was used for a
successful delivery of some other message. This seems entirely
reasonable: after all the message is NOT "waiting for some host".
This is so "obvious" that I'm not sure why it wasn't done
previously. Hope I haven't missed anything, but it can't do any
harm, as the worst effect is to miss an optimization.
(ii) If, despite (i), such a delivery is accidentally attempted, the
routing retry time is respected, so at least it doesn't keep
hammering the server.
PH/31 Installed Andrew Findlay's patch to close the writing end of the socket
in ${readsocket because some servers need this prod.
PH/32 Added some extra debug output when updating a wait-xxx database.
PH/33 The hint "could be header name not terminated by colon", which has been
given for certain expansion errors for a long time, was not being given
for the ${if def:h_colon_omitted{... case.
PH/34 The spec says: "With one important exception, whenever a domain list is
being scanned, $domain contains the subject domain." There was at least
one case where this was not true.
PH/35 The error "getsockname() failed: connection reset by peer" was being
written to the panic log as well as the main log, but it isn't really
panic-worthy as it just means the connection died rather early on. I have
removed the panic log writing for the ECONNRESET error when getsockname()
fails.
PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
runs only) independently of the message's sender address. This meant
that, if the 4xx error was in fact related to the sender, a different
message to the same recipient with a different sender could confuse
things. In particualar, this can happen when sending to a greylisting
server, but other circumstances could also provoke similar problems.
I have changed the default so that the retry time for these errors is now
based a combination of the sender and recipient addresses. This change
can be overridden by setting address_retry_include_sender=false in the
smtp transport.
PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the
remote server are returned as part of bounce messages. This was not
happening for LMTP over a pipe (the lmtp transport), but now it is the
same for both kinds of LMTP.
PH/38 Despite being documented as not happening, Exim was rewriting addresses
in header lines that were in fact CNAMEs. This is no longer the case.
PH/39 If -R or -S was given with -q<time>, the effect of -R or -S was ignored,
and queue runs started by the daemon processed all messages. This has
been fixed so that -R and -S can now usefully be given with -q<time>.
PH/40 Import PCRE release 6.7 (fixes some bugs).
PH/41 Add bitwise logical operations to eval (courtesy Brad Jorsch).
PH/42 Give an error if -q is specified more than once.
PH/43 Renamed the variables $interface_address and $interface_port as
$received_ip_address and $received_port, to make it clear that these
values apply to message reception, and not to the outgoing interface when
a message is delivered. (The old names remain recognized, of course.)
PH/44 There was no timeout on the connect() call when using a Unix domain
socket in the ${readsocket expansion. There now is.
PH/45 Applied a modified version of Brad Jorsch's patch to allow "message" to
be meaningful with "accept".
SC/01 Eximstats V1.43
Bug fix for V1.42 with -h0 specified. Spotted by Chris Lear.
SC/02 Eximstats V1.44
Use a glob alias rather than an array ref in the generated
parser. This improves both readability and performance.
SC/03 Eximstats V1.45 (Marco Gaiarin / Steve Campbell)
Collect SpamAssassin and rejection statistics.
Don't display local sender or destination tables unless
there is data to show.
Added average volumes into the top table text output.
SC/04 Eximstats V1.46
Collect data on the number of addresses (recipients)
as well as the number of messages.
SC/05 Eximstats V1.47
Added 'Message too big' to the list of mail rejection
reasons (thanks to Marco Gaiarin).
SC/06 Eximstats V1.48
Mainlog lines which have GMT offsets and are too short to
have a flag are now skipped.
SC/07 Eximstats V1.49 (Alain Williams)
Added the -emptyok flag.
SC/08 Eximstats V1.50
Fixes for obtaining the IP address from reject messages.
JJ/03 exipick.20061117.2, made header handling as similar to exim as possible
(added [br]h_ prefixes, implemented RFC2047 decoding. Fixed
whitesspace changes from 4.64-PH/27
JJ/04 exipick.20061117.2, fixed format and added $message_headers_raw to
match 4.64-PH/13
JJ/05 exipick.20061117.2, bug fixes (error out sooner when invalid criteria
are found, allow negative numbers in numeric criteria)
JJ/06 exipick.20061117.2, added new $message_body_missing variable
JJ/07 exipick.20061117.2, added $received_ip_address and $received_port
to match changes made in 4.64-PH/43
PH/46 Applied Jori Hamalainen's patch to add features to exiqsumm.
PH/47 Put in an explicit test for a DNS lookup of an address record where the
"domain" is actually an IP address, and force a failure. This locks out
those revolvers/nameservers that support "A-for-A" lookups, in
contravention of the specifications.
PH/48 When a host name was looked up from an IP address, and the subsequent
forward lookup of the name timed out, the host name was left in
$sender_host_name, contrary to the specification.
PH/49 Although default lookup types such as lsearch* or cdb*@ have always been
restricted to single-key lookups, Exim was not diagnosing an error if
* or *@ was used with a query-style lookup.
PH/50 Increased the value of DH_BITS in tls-gnu.c from 768 to 1024.
MH/01 local_scan ABI version incremented to 1.1. It should have been updated
long ago, but noone interested enough thought of it. Let's just say that
the "1.1" means that there are some new functions that weren't there at
some point in the past.
PH/51 Error processing for expansion failure of helo_data from an smtp
transport during callout processing was broken.
PH/52 Applied John Jetmore's patch to allow tls-on-connect and STARTTLS to be
tested/used via the -bh/-bhc/-bs options.
PH/53 Added missing "#include <time.h>" to pcre/pcretest.c (this was a PCRE
bug, fixed in subsequent PCRE releases).
PH/54 Applied Robert Bannocks' patch to avoid a problem with references that
arises when using the Solaris LDAP libraries (but not with OpenLDAP).
PH/55 Check for a ridiculously long file name in exim_dbmbuild.

SC/01 Use a glob alias rather than an array ref in eximstats generated
parser. This improves both readability and performance.
SC/02 Collect SpamAssassin and rejection statistics in eximstats.
Don't display local sender or destination tables in eximstats unless
there is data to show.
Added average volumes into the eximstats top table text output.
SC/03 Collect data on the number of addresses (recipients) as well
as the number of messages in eximstats.
TF/01 Correct an error in the documentation for the redirect router. Exim
does (usually) call initgroups() when daemonizing.
TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs
with consistent privilege compared to when running as a daemon.
TF/03 Note in the spec that $authenticated_id is not set for local
submissions from trusted users.
TF/04 The ratelimit per_rcpt option now works correctly in acl_not_smtp.
Thanks to Dean Brooks for the patch.
TF/05 Make it easier to get SMTP authentication and TLS/SSL support working
by adding some example configuration directives to the default
configuration file. A little bit of work is required to uncomment the
directives and define how usernames and passwords are checked, but
there is now a framework to start from.
PH/01 Added #define LDAP_DEPRECATED 1 to ldap.c because some of the "old"
functions that Exim currently uses aren't defined in ldap.h for OpenLDAP
without this. I don't know how relevant this is to other LDAP libraries.
PH/02 Add the verb name to the "unknown ACL verb" error.
PH/03 Magnus Holmgren's patch for filter_prepend_home.
PH/03 Fixed Bugzilla #101: macro definition between ACLs doesn't work.
PH/04 Applied Magnus Holmgren's patch to fix Bugzilla #98: transport's home
directory not expanded when it should be if an expanded home directory
was set for the address (which is overridden by the transport).
PH/05 Applied Alex Kiernan's patch to fix Bugzilla #99: a problem with
libradius.
PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the
bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL,
because it is too late at that time, and has no effect.
PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a
security issue with \' (bugzilla #107). I could not use the
PQescapeStringConn() function, because it needs a PGconn value as one of
its arguments.
PH/08 When testing addresses using -bt, indicate those final addresses that
are duplicates that would not cause an additional delivery. At least one
person was confused, thinking that -bt output corresponded to deliveries.
(Suppressing duplicates isn't a good idea as you lose the information
about possibly different redirections that led to the duplicates.)
PH/09 Applied patch from Erik to use select() instead of poll() in spam.c on
systems where poll() doesn't work, in particular OS X.
PH/10 Added more information to debugging output for retry time not reached.
PH/11 Applied patch from Arkadiusz Miskiewicz to apply a timeout to read
operations in malware.c.
PH/12 Applied patch from Magnus Holmgren to include the "h" tag in Domain Keys
signatures.
PH/13 If write_rejectlog was set false when logging was sent to syslog with
syslog_duplication set false, log lines that would normally be written
both the the main log and to the reject log were not written to syslog at
all.
PH/14 In the default configuration, change the use of "message" in ACL warn
statements to "add_header".
PH/15 Diagnose a filter syntax error for "seen", "unseen", or "noerror" if not
not followed by a command (e.g. "seen endif").
PH/16 Recognize SMTP codes at the start of "message" in ACLs and after :fail:
and :defer: in a redirect router. Add forbid_smtp_code to suppress the
latter.
PH/17 Added extra conditions to the default value of delay_warning_condition
so that it is now:
${if or { \
{ !eq{$h_list-id:$h_list-post:$h_list-subscribe:}{} } \
{ match{$h_precedence:}{(?i)bulk|list|junk} } \
{ match{$h_auto-submitted:}{(?i)auto-generated|auto-replied} } \
}{no}{yes}}
The Auto-Submitted: and various List- headers are standardised, whereas I
don't think Precedence: ever was.
PH/18 Refactored debugging code in route_finduser() to show more information,
in particular, the error code if getpwnam() issues one.
PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module.
This is apparently needed in addition to the PH/07 change above to avoid
any possible encoding problems.
PH/20 Perl can change the locale. Exim was resetting it after a ${perl call,
but not after initializing Perl.
PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and
output them only if debugging. By default they are written stderr,
apparently, which is not desirable.
PH/22 Added Alain Williams' LDAP patch to support setting REFERRALS=off on
queries.
JJ/01 exipick: added --reverse (and -R synonym), --random, --size, --sort and
--not options
JJ/02 exipick: rewrote --help documentation to hopefully make more clear.
PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is
authenticated or an ident call has been made. Suppress the default
values for $authenticated_id and $authenticated_sender (but permit -oMai
and -oMas) when testing with -bh.
PH/24 Re-jigged the order of the tests in the default configuration so that the
tests for valid domains and recipients precede the DNS black list and CSA
tests, on the grounds that those ones are more expensive.
PH/25 Exim was not testing for a space following SMTP commands such as EHLO
that require one. Thus, EHLORHUBARB was interpreted as a valid command.
This bug exists in every version of Exim that I still have, right back to
0.12.
PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
However, an attempt to turn on case-sensitivity in a regex key by
including (?-i) didn't work because the subject string was already
lowercased, and the effects were non-intuitive. It turns out that a
one-line patch can be used to allow (?-i) to work as expected.

Exim version 4.62
-----------------
TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst
other effects) broke the use of negated acl sub-conditions.
PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore
patch).
PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
"Deny" causes Exim to reject the incoming connection with a 554 error.
Unfortunately, if there is a major crisis, such as a disk failure,
tcp-wrappers gives "deny", whereas what one would like would be some
kind of temporary error. A kludge has been added to help with this.
Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
554 error is used if errno is still zero or contains ENOENT (which occurs
if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
451 error is used.
PH/03 Add -lutil to the default FreeBSD LIBS setting.
PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host
errors. Otherwise a message that provokes a temporary error (when other
messages do not) can cause a whole host to time out.
PH/05 Batch deliveries by appendfile and pipe transports did not work when the
addresses were routed directly to files or pipes from a redirect router.
File deliveries just didn't batch; pipe deliveries might have suffered
odd errors.
PH/06 A failure to get a lock for a hints database would erroneously always say
"Failed to get write lock", even when it was really a read lock.
PH/07 The appendfile transport was creating MBX lock files with a fixed mode
of 0600. This has been changed to use the value of the lockfile_mode
option (which defaults to 0600).
PH/08 Applied small patch from the Sieve maintainer.
PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
folder from quota calculations, a direct delivery into this folder messed
up the contents of the maildirsize file. This was because the regex was
used only to exclude .Trash (or whatever) when the size of the mailbox
was calculated. There was no check that a delivery was happening into an
excluded directory. This bug has been fixed by ignoring all quota
processing for deliveries into excluded directories.
PH/10 Added the maildirfolder_create_regex option to appendfile.
Exim version 4.61
-----------------
PH/01 The code for finding all the local interface addresses on a FreeBSD
system running IPv6 was broken. This may well have applied to all BSD
systems, as well as to others that have similar system calls. The broken
code found IPv4 interfaces correctly, but gave incorrect values for the
IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
that it would not match correctly against @[] and not recognize the IPv6
addresses as local.
PH/02 The ipliteral router was not recognizing addresses of the form user@
[ipv6:....] because it didn't know about the "ipv6:" prefix.
PH/03 Added disable_ipv6.
PH/04 Changed $reply_address to use the raw form of the headers instead of the
decoded form, because it is most often used to construct To: headers
lines in autoreplies, and the decoded form may well be syntactically
invalid. However, $reply_address has leading white space removed, and all
newlines turned into spaces so that the autoreply transport does not
grumble.
PH/05 If group was specified without a user on a router, and no group or user
was specified on a transport, the group from the router was ignored.
PH/06 Increased the number of ACL variables to 20 of each type, and arranged
for visible compile-time settings that can be used to change these
numbers, for those that want even more. Backwards compatibility with old
spool files has been maintained. However, going back to a previous Exim
release will lost any variables that are in spool files.
PH/07 Two small changes when running in the test harness: increase delay when
passing a TCP/IP connection to a new process, in case the original
process has to generate a bounce, and remove special handling of
127.0.0.2 (sic), which is no longer necessary.
PH/08 Changed debug output of dbfn_open() flags from numbers to names, so as to
be the same on different OS.
PH/09 Moved a debug statement in filter processing to avoid a race problem when
testing.
JJ/01 exipick: fixed bug where -b (brief) output option showed "Vars:"
whether --show-vars was specified or not
JJ/02 exipick: Added support for new ACL variable spool format introduced
in 4.61-PH/06
PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
syntactically invalid From: or Reply-to: line, and a filter used this to
generate an autoreply, and therefore failed to obtain an address for the
autoreply, Exim could try to deliver to a non-existent relative file
name, causing unrelated and misleading errors. What now happens is that
it logs this as a hard delivery error, but does not attempt to create a
bounce message.
PH/11 The exinext utility has a -C option for testing purposes, but although
the given file was scanned by exinext itself; it wasn't being passed on
when Exim was called.
PH/12 In the smtp transport, treat an explicit ECONNRESET error the same as
an end-of-file indication when reading a command response.
PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
compiled. In many other places in Exim, IPv6 addresses are always
recognized, so I have changed this. It also means that IPv4 domain
literals of the form [IPV4:n.n.n.n] are now always recognized.
PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
used if the router is not running as root, for example, when verifying at
ACL time, or when using -bh. The debugging output from this situation was
non-existent - all you got was a failure to exec. I have made two
changes:
(a) Failures to set uid/gid, the current directory, or a process leader
in a subprocess such as that created by queryprogram now generate
suitable debugging ouput when -d is set.
(b) The queryprogram router detects when it is not running as root,
outputs suitable debugging information if -d is set, and then runs
the subprocess without attempting to change uid/gid.
PH/15 Minor change to Makefile for building test_host (undocumented testing
feature).
PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
additional section of a DNS packet that returns MX or SRV records.
Instead, it always explicitly searches for A/AAAA records. This avoids
major problems that occur when a DNS server includes only records of one
type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
fixed another bug: if SRV records were looked up and the corresponding
address records were *not* found in the additional section, the port
values from the SRV records were lost.
PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
using the correct key (the original address) when searching the retry
rules in order to find which one to use for generating the retry hint.
PH/18 If quota_warn_message contains a From: header, Exim now refrains from
adding the default one. Similarly, if it contains a Reply-To: header, the
errors_reply_to option, if set, is not used.
PH/19 When calculating a retry time, Exim used to measure the "time since
failure" by looking at the "first failed" field in the retry record. Now
it does not use this if it is later than than the arrival time of the
message. Instead it uses the arrival time. This makes for better
behaviour in cases where some deliveries succeed, thus re-setting the
"first failed" field. An example is a quota failure for a huge message
when small messages continue to be delivered. Without this change, the
"time since failure" will always be short, possible causing more frequent
delivery attempts for the huge message than are intended.
[Note: This change was subsequently modified - see PH/04 for 4.62.]
PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
$1, $2, $3) because the numerical variables can be reset during some
expansion items (e.g. "match"), thereby losing the authentication data.
PH/21 Make -bV show the size of off_t variables so that the test suite can
decide whether to run tests for quotas > 2G.
PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
mailbox_size, and mailbox_filecount in the appendfile transport. If a
filecount value is greater than 2G or if a quota value is greater than 2G
on a system where the size of off_t is not greater than 4, a panic error
is given.
PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
never match. The debug and -bh output now contains an explicit error
message indicating a malformed IPv4 address or mask.
PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
1.2.3.4 without a mask. Now it is not recognized as an IP address, and
PH/23 above applies.
PH/25 Do not write to syslog when running in the test harness. The only
occasion when this arises is a failure to open the main or panic logs
(for which there is an explicit test).
PH/26 Added the /no_tell option to "control=freeze".
PH/27 If a host name lookup failed very early in a connection, for example, if
the IP address matched host_lookup and the reverse lookup yielded a name
that did not have a forward lookup, an error message of the form "no IP
address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
could be logged. Now it outputs the IP address instead of "NULL".
PH/28 An enabling patch from MH: add new function child_open_exim2() which
allows the sender and the authenticated sender to be set when
submitting a message from within Exim. Since child_open_exim() is
documented for local_scan(), the new function should be too.
PH/29 In GnuTLS, a forced expansion failure for tls_privatekey was not being
ignored. In both GnuTLS and OpenSSL, an expansion of tls_privatekey that
results in an empty string is now treated as unset.
PH/30 Fix eximon buffer overflow bug (Bugzilla #73).
PH/31 Added sender_verify_fail logging option.
PH/32 In November 2003, the code in Exim that added an empty Bcc: header when
needed by RFC 822 but not by RFC 2822 was commented out. I have now
tidied the source and removed it altogether.
PH/33 When a queue run was abandoned because the load average was too high, a
log line was always written; now it is written only if the queue_run log
selector is set. In addition, the log line for abandonment now contains
information about the queue run such as the pid. This is always present
in "start" and "stop" lines but was omitted from the "abandon" line.
PH/34 Omit spaces between a header name and the colon in the error message that
is given when verify = headers_syntax fails (if there are lots of them,
the message gets confusing).
PH/35 Change the default for dns_check_names_pattern to allow slashes within
names, as there are now some PTR records that contain slashes. This check
is only to protect against broken name servers that fall over on strange
characters, so the fact that it applies to all lookups doesn't matter.
PH/36 Now that the new test suite is complete, we can remove some of the
special code in Exim that was needed for the old test suite. For example,
sorting DNS records because real resolvers return them in an arbitrary
order. The new test suite's fake resolver always returns records in the
same order.
PH/37 When running in the test harness, use -odi for submitted messages (e.g.
bounces) except when queue_only is set, to avoid logging races between
the different processes.
PH/38 Panic-die if .include specifies a non-absolute path.
PH/39 A tweak to the "H" retry rule from its user.
JJ/03 exipick: Removed parentheses from 'next' and 'last' calls that specified
a label. They prevented compilation on older perls.
JJ/04 exipick: Refactored code to prevent implicit split to @_ which caused
a warning to be raised on newish perls.
JJ/05 exipick: Fixed bug where -bpc always showed a count of all messages
on queue. Changes to match documented behaviour of showing count of
messages matching specified criteria.
PH/40 Changed the default ident timeout from 30s to 5s.
PH/41 Added support for the use of login_cap features, on those BSD systems
that have them, for controlling the resources used by pipe deliveries.
PH/42 The content-scanning code uses fopen() to create files in which to put
message data. Previously it was not paying any attention to the mode of
the files. Exim runs with umask(0) because the rest of the code creates
files with open(), and sets the required mode explicitly. Thus, these
files were ending up world-writeable. This was not a big issue, because,
being within the spool directory, they were not world-accessible. I have
created a function called modefopen, which takes an additional mode
argument. It sets umask(777), creates the file, chmods it to the required
mode, then resets the umask. All the relevant calls to fopen() in the
content scanning code have been changed to use this function.
PH/43 If retry_interval_max is set greater than 24 hours, it is quietly reset
to 24 hours. This avoids potential overflow problems when processing G
and H retry rules. I suspect nobody ever tinkers with this value.
PH/44 Added STRIP_COMMAND=/usr/bin/strip to the FreeBSD Makefile.
PH/45 When the plaintext authenticator is running as a client, the server's
challenges are checked to ensure they are valid base64 strings. By
default, the authentication attempt is cancelled if an invalid string is
received. Setting client_ignore_invalid_base64 true ignores these errors.
The decoded challenge strings are now placed in $auth1, $auth2, etc. as
they are received. Thus, the responses can be made to depend on the
challenges. If an invalid string is ignored, an empty string is placed in
the variable.
PH/46 Messages that are created by the autoreply transport now contains a
References: header, in accordance with RFCs 2822 and 3834.
PH/47 Added authenticated_sender_force to the smtp transport.
PH/48 The ${prvs expansion was broken on systems where time_t was long long.
PH/49 Installed latest patch from the Sieve maintainer.
PH/50 When an Exim quota was set without a file count quota, and mailbox_size
was also set, the appendfile transport was unnecessarily scanning a
directory of message files (e.g. for maildir delivery) to find the count
of files (along with the size), even though it did not need this
information. It now does the scan only if it needs to find either the
size of the count of files.
PH/51 Added ${time_eval: to convert Exim time strings into seconds.
PH/52 Two bugs concerned with error handling when the smtp transport is
used in LMTP mode:
(i) Exim was not creating retry information for temporary errors given
for individual recipients after the DATA command when the smtp transport
was used in LMTP mode. This meant that they could be retried too
frequently, and not timed out correctly.
(ii) Exim was setting the flag that allows error details to be returned
for LMTP errors on RCPT commands, but not for LMTP errors for individual
recipients that were returned after the DATA command.
PH/53 This is related to PH/52, but is more general: for any failing address,
when detailed error information was permitted to be returned to the
sender, but the error was temporary, then after the final timeout, only
"retry timeout exceeded" was returned. Now it returns the full error as
well as "retry timeout exceeded".
PH/54 Added control=allow_auth_unadvertised, as it seems there are clients that
do this, and (what is worse) MTAs that accept it.
PH/55 Added the add_header modified to ACLs. The use of "message" with "warn"
will now be deprecated.
PH/56 New os.c-cygwin from the Cygwin maintainer.
JJ/06 exipick: added --unsorted option to allow unsorted output in all output
formats (previously only available in exim formats via -bpr, -bpru,
and -bpra. Now also available in native and exiqgrep formats)
JJ/07 exipick: added --freeze and --thaw options to allow faster interaction
with very large, slow to parse queues
JJ/08 exipick: added ! as generic prefix to negate any criteria format
JJ/09 exipick: miscellaneous performance enhancements (~24% improvements)
PH/57 Tidies in SMTP dialogue display in debug output: (i) It was not showing
responses to authentication challenges, though it was showing the
challenges; (ii) I've removed the CR characters from the debug output for
SMTP output lines.
PH/58 Allow for the insertion of a newline as well as a space when a string
is turned into more than one encoded-word during RFC 2047 encoding. The
Sieve code now uses this.
PH/59 Added the following errors that can be detected in retry rules: mail_4xx,
data_4xx, lost_connection, tls_required.
PH/60 When a VRFY deferred or FAILED, the log message rather than the user
message was being sent as an SMTP response.
PH/61 Add -l and -k options to exicyclog.
PH/62 When verifying, if an address was redirected to one new address, so that
verification continued, and the new address failed or deferred after
having set something in $address_data, the value of $address_data was not
passed back to the ACL. This was different to the case when no
redirection occurred. The value is now passed back in both cases.
PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
HAVE_SETCLASSRESOURCES because there are different APIs in use that all
use login_cap.h, so on its own it isn't the distinguishing feature. The
new name refers directly to the setclassresources() function.
PH/65 Added configuration files for NetBSD3.
PH/66 Updated OS/Makefile-HP-UX for gcc 4.1.0 with HP-UX 11.
PH/67 Fixed minor infelicity in the sorting of addresses to ensure that IPv6
is preferred over IPv4.
PH/68 The bounce_return_message and bounce_return_body options were not being
honoured for bounces generated during the reception of non-SMTP messages.
In particular, this applied to messages rejected by the ACL. This bug has
been fixed. However, if bounce_return_message is true and bounce_return_
body is false, the headers that are returned for a non-SMTP message
include only those that have been read before the error was detected.
(In the case of an ACL rejection, they have all been read.)
PH/69 The HTML version of the specification is now built in a directory called
spec_html instead of spec.html, because the latter looks like a path with
a MIME-type, and this confuses some software.
PH/70 Catch two compiler warnings in sieve.c.
PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
function verify_get_ident() calls ip_connect() to connect a socket, but
if the "connect()" function timed out, ip_connect() used to close the
socket. However, verify_get_ident() also closes the socket later, and in
between Exim writes to the log, which may get opened at this point. When
the socket was closed in ip_connect(), the log could get the same file
descriptor number as the socket. This naturally causes chaos. The fix is
not to close the socket in ip_connect(); the socket should be closed by
the function that creates it. There was only one place in the code where
this was missing, in the iplookup router, which I don't think anybody now
uses, but I've fixed it anyway.
PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as
well as to direct DNS lookups. Otherwise the handling of names in host
lists is inconsistent and therefore confusing.
Exim version 4.60
-----------------
PH/01 Two changes to the default runtime configuration:
(1) Move the checks for relay_from_hosts and authenticated clients from
after to before the (commented out) DNS black list checks.
(2) Add control=submission to the relay_from_hosts and authenticated
clients checks, on the grounds that messages accepted by these
statements are most likely to be submissions.
PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
(1) Generate an error if the third argument for the ${prvs expansion is
not a single digit.
(2) Treat a missing third argument of ${prvscheck as if it were an empty
string.
(3) Reset the variables that are obtained from the first argument of
${prvscheck and used in the second argument before leaving the code,
because their memory is reclaimed, so using them afterwards may do
silly things.
(4) Tidy up the code for expanding the arguments of ${prvscheck one by
one (it's much easier than Tom thought :-).
(5) Because of (4), we can now allow for the use of $prvscheck_result
inside the third argument.
PH/03 For some reason, the default setting of PATH when running a command from
a pipe transport was just "/usr/bin". I have changed it to
"/bin:/usr/bin".
PH/04 SUPPORT_TRANSLATE_IP_ADDRESS and MOVE_FROZEN_MESSAGES did not cause
anything to be listed in the output from -bV.
PH/05 When a filter generated an autoreply, the entire To: header line was
quoted in the delivery log line, like this:
=> >A.N.Other <ano@some.domain> <original@ddress> ...
This has been changed so that it extracts the operative address. There
may be more than one such address. If so, they are comma-separated, like
this:
=> >ano@some.domain,ona@other.domain <original@ddress> ...
PH/06 When a client host used a correct literal IP address in a HELO or EHLO
command, (for example, EHLO [1.2.3.4]) and the client's IP address was
not being looked up in the rDNS to get a host name, Exim was showing the
IP address twice in Received: lines, even though the IP addresses were
identical. For example:
Received: from [1.2.3.4] (helo=[1.2.3.4])
However, if the real host name was known, it was omitting the HELO data
if it matched the actual IP address. This has been tidied up so that it
doesn't show the same IP address twice.
PH/07 When both +timestamp and +memory debugging was on, the value given by
$tod_xxx expansions could be wrong, because the tod_stamp() function was
called by the debug printing, thereby overwriting the timestamp buffer.
Debugging no longer uses the tod_stamp() function when +timestamp is set.
PH/08 When the original message was included in an autoreply transport, it
always said "this is a copy of the message, including all the headers",
even if body_only or headers_only was set. It now gives an appropriate
message.
PH/09 Applied a patch from the Sieve maintainer which:
o fixes some comments
o adds the (disabled) notify extension core
o adds some debug output for the result of if/elsif tests
o points to the current vacation draft in the documentation
and documents the missing references header update
and most important:
o fixes a bug in processing the envelope test (when testing
multiple envelope elements, the last element determinted the
result)
PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
Electronic Mail") by including:
Auto-submitted: auto-generated
in the messages that it generates (bounce messages and others, such as
warnings). In the case of bounce messages for non-SMTP mesages, there was
also a typo: it was using "Auto_submitted" (underscore instead of
hyphen). Since every message generated by Exim is necessarily in response
to another message, thes have all been changed to:
Auto-Submitted: auto-replied
in accordance with these statements in the RFC:
The auto-replied keyword:
- SHOULD be used on messages sent in direct response to another
message by an automatic process,
- MUST NOT be used on manually-generated messages,
- MAY be used on Delivery Status Notifications (DSNs) and Message
Disposition Notifications (MDNs),
- MUST NOT be used on messages generated by automatic or periodic
processes, except for messages which are automatic responses to
other messages.
PH/11 Added "${if def:sender_address {(envelope-from <$sender_address>)\n\t}}"
to the default Received: header definition.
PH/12 Added log selector acl_warn_skipped (default on).
PH/13 After a successful wildlsearch lookup, discard the values of numeric
variables because (a) they are in the wrong storage pool and (b) even if
they were copied, it wouldn't work properly because of the caching.
PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length
checking when decoding. Apparently there are clients that generate
overlong encoded strings. Why am I not surprised?
PH/15 If the first argument of "${if match_address" was not empty, but did not
contain an "@" character, Exim crashed. Now it writes a panic log message
and treats the condition as false.
PH/16 In autoreply, treat an empty string for "once" the same as unset.
PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
extension "envelope-auth". The code is finished and in agreement with
other implementations, but there is no documentation so far and in fact,
nobody wrote the draft yet. This extension is currently #undef'ed, thus
not changing the active code.
Print executed "if" and "elsif" statements when debugging is used. This
helps a great deal to understand what a filter does.
Document more things not specified clearly in RFC3028. I had all this
sorted out, when out of a sudden new issues came to my mind. Oops."
PH/18 Exim was not recognizing the "net-" search type prefix in match_ip lists
(Bugzilla #53).
PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
canonical form (as documented). However, after a host name lookup from
the IP address, check_host() was doing a simple string comparison with
addresses acquired from the DNS when checking that the found name did
have the original IP as one of its addresses. Since any found IPv6
addresses are likely to be in abbreviated form, the comparison could
fail. Luckily, there already exists a function for doing the comparison
by converting both addresses to binary, so now that is used instead of
the text comparison.
PH/20 There was another similar case to PH/19, when a complete host name was
given in a host list; looking up its IP address could give an abbreviated
form, whereas the current host's name might or might not be abbreviated.
The same fix has been applied.

Exim version 4.54
-----------------
PH/01 The ${base62: operator adjusted itself to base 36 when BASE_62 was
set to 36 (for Darwin and Cygwin), but the ${base62d: operator did not.
It now does.
PH/02 Two minor problems detected in Cygwin: the os.{c,h} files had lost */ on
the CVS lines, and there was a missing #if HAVE_IPV6 in host.c.
PH/03 Typo: missing ".o" in src/pcre/Makefile.
PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
header line, restrict the check to what is listed in RFCs 2369 and 2929.
Also, for "Auto-Submitted", treat anything other than "no" as
non-personal, in accordance with RFC 3834. (Previously it treated
anything starting "auto-" as non-personal.)
TF/01 The control=submission/name=... option had a problem with syntax
errors if the name included a slash character. The /name= option
now slurps the rest of the string, so it can include any characters
but it must come last in the list of options (after /sender_retain
or /domain=).
PH/05 Some modifications to the interface to the fake nameserver for the new
testing suite.
Exim version 4.53
-----------------
TK/01 Added the "success_on_redirect" address verification option. See
NewStuff for rationale and an example.
PH/01 Added support for SQLite, basic code supplied by David Woodhouse.
PH/02 Patch to exigrep to allow it to work on syslog lines.
PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
fread() to skip over the body file's header line, because in Cygwin the
header line is locked and is inaccessible.
PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
co-exist for some time) to make it clear that it is the Exim ID that is
referenced, not the Message-ID: header line.
PH/05 Replaced all Tom's calls to snprintf() with calls to the internal
string_format() function, because snprintf() does not exist on all
operating systems.
PH/06 The use of forbid_filter_existstest now also locks out the use of the
${stat: expansion item.
PH/07 Changed "SMTP protocol violation: synchronization error" into "SMTP
protocol synchronization error", to keep the pedants happy.
PH/08 Arrange for USE_INET_NTOA_FIX to be set in config.h for AIX systems as
well as for IRIX systems, when gcc is being used. See the host.c source
file for comments.
PH/09 Installed latest Cygwin configuration files from the Cygwin maintainer.
PH/10 Named domain lists were not working if used in a queue_smtp_domains
setting.
PH/11 Added support for the IGNOREQUOTA extension to LMTP, both to the lmtp
transport and to the smtp transport in LMTP mode.
TK/02 Remove one case of BASE64 error detection FTTB (undocumented anyway).
PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
run a filter in a subprocess. This could lead to confusion in subsequent
lookups in the parent process. There should also be a search_tidyup() at
the end of the subprocess.
PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
only if the host matched helo_try_verify_hosts, which caused the
verification to occur when the EHLO/HELO command was issued. The ACL just
tested the remembered result. Now, if a previous verification attempt has
not happened, "verify = helo" does it there and then.
JJ/01 exipick: added $message_exim_id variable (see 4.53-PH/04)
TK/03 Fix log output including CR from clamd.
PH/14 A reference to $reply_address when Reply-to: was empty and From: did not
exist provoked a memory error which could cause a segfault.
PH/15 Installed PCRE 6.2
PH/17 Defined BIND_8_COMPAT in the Darwin os.h file.
PH/18 Reversed 4.52/PH/17 because the HP-UX user found it wasn't the cause
of the problem. Specifically, suggested +O2 rather than +O1 for the
HP-UX compiler.
PH/19 Added sqlite_lock_timeout option (David Woodhouse's patch).
PH/20 If a delivery was routed to a non-standard port by means of an SRV
record, the port was not correctly logged when the outgoing_port log
selector was set (it logged the transort's default port).
PH/21 Added support for host-specific ports to manualroute, queryprogram,
fallback_hosts, and "hosts" in the smtp transport.
PH/22 If the log selector "outgoing_port" is set, the port is now also given on
host errors such as "Connection refused".
PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
authentication with radiusclient 0.4.9:
- Error returned from rc_read_config was caught wrongly
- Username/password not passed on to radius server due to wrong length.
The presumption is that some radiusclient API changes for 4.51/PH/17
were not taken care of correctly. The code is still untested by me (my
Linux distribution still has 0.3.2 of radiusclient), but it was
contributed by a Radius user.
PH/24 When doing a callout, the value of $domain wasn't set correctly when
expanding the "port" option of the smtp transport.
TK/04 MIME ACL: Fix buffer underrun that occurs when EOF condition is met
while reading a MIME header. Thanks to Tom Hughes for a patch.
PH/24 Include config.h inside local_scan.h so that configuration settings are
available.
PH/25 Make $smtp_command_argument available after all SMTP commands. This means
that in an ACL for RCPT (for example), you can examine exactly what was
received.
PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
commands, but it was not correctly comparing the address with the actual
client host address. Thus, it would show the EHLO address in Received:
header lines when this was not necessary.
PH/27 Added the % operator to ${eval:}.
PH/28 Exim tries to create and chdir to its spool directory when it starts;
it should be ignoring failures (because with -C, for example, it has lost
privilege). It wasn't ignoring creation failures other than "already
exists".
PH/29 Added "crypteq" to the list of supported features that Exim outputs when
-bV or -d is used.
PH/30 Fixed (presumably very longstanding) bug in exim_dbmbuild: if it failed
because an input line was too long, either on its own, or by virtue of
too many continuations, the temporary file was not being removed, and the
return code was incorrect.
PH/31 Missing "BOOL" in function definition in filtertest.c.
PH/32 Applied Sieve patches from the maintainer.
TK/05 Domainkeys: Accomodate for a minor API change in libdomainkeys 0.67.
PH/33 Added "verify = not_blind".
PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
Local/Makefile (with some defaults set). These are used in built scripts
such as exicyclog, but they have never been used in the exim_install
script (though there are many overriding facilities there). I have
arranged that the exim_install script now takes note of these two
settings.
PH/35 Installed configuration files for Dragonfly.
PH/36 When a locally submitted message by a trusted user did not contain a
From: header, and the sender address was obtained from -f or from an SMTP
MAIL command, and the trusted user did not use -F to supply a sender
name, $originator_name was incorrectly used when constructing a From:
header. Furthermore, $originator_name was used for submission mode
messages from external hosts without From: headers in a similar way,
which is clearly wrong.
PH/37 Added control=suppress_local_fixups.
PH/38 When log_selector = +received_sender was set, and the addition of the
sender made the log line's construction buffer exactly full, or one byte
less than full, an overflow happened when the terminating "\n" was
subsequently added.
PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
when the result of a list match is failure because a DNS lookup failed.
PH/40 RM_COMMAND is now used in the building process.
PH/41 Added a "distclean" target to the top-level Makefile; it deletes all
the "build-* directories that it finds.
PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
address in a domain literal was a prefix of an interface address.
PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
when verifying a sender address, unless rewrite_headers is false.
PH/44 Wrote a long comment about why errors_to addresses are verified as
recipients, not senders.
TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when
the ratelimit ACL was added.
PH/45 Added $smtp_command for the full command (cf $smtp_command_argument).
PH/46 Added extra information about PostgreSQL errors to the error string.
PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
avoiding the need to install special zones in a real server. This is
backwards compatible; if it can't find the fake resolver, it drops back.
Thus, both old and new test suites can be run.
TF/02 Added util/ratelimit.pl
TF/03 Minor fix to the ratelimit code to improve its behaviour in case the
clock is set back in time.
TF/04 Fix the ratelimit support in exim_fixdb. Patch provided by Brian
Candler <B.Candler@pobox.com>.
TF/05 The fix for PH/43 was not completely correct; widen_domains is always
OK for addresses that are the result of redirections.
PH/48 A number of further additions for the benefit of the new test suite,
including a fake gethostbyname() that interfaces to the fake DNS resolver
(see PH/47 above).
TF/06 The fix for widen_domains has also been applied to qualify_single and
search_parents which are the other dnslookup options that can cause
header rewrites.
PH/49 Michael Haardt's randomized retrying, but as a separate retry parameter
type ("H").
PH/50 Make never_users, trusted_users, admin_groups, trusted_groups expandable.
TF/07 Exim produced the error message "an SRV record indicated no SMTP
service" if it encountered an MX record with an empty target hostname.
The message is now "an MX or SRV record indicated no SMTP service".
TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
if the DNS of the sending site is misconfigured. This is quite a
common situation. This change restores the behaviour of treating a
helo verification defer as a failure.
PH/51 If self=fail was set on a router, the bounce message did not include the
actual error message.
