Exim version 4.80.1
-------------------
PP/01 SECURITY: protect DKIM DNS decoding from remote exploit.
CVE-2012-5671
This, or similar/improved, will also be change PP/11 of 4.81.
See: https://secunia.com/advisories/51098/

are called p5-*.
I hope that's all of them.
|
|
|
|
1. New authenticator driver, "gsasl". Server-only (at present).
This is a SASL interface, licensed under GPL, which can be found at
http://www.gnu.org/software/gsasl/.
This system does not provide sources of data for authentication, so
careful use needs to be made of the conditions in Exim.
2. New authenticator driver, "heimdal_gssapi". Server-only.
A replacement for using cyrus_sasl with Heimdal, now that $KRB5_KTNAME
is no longer honoured for setuid programs by Heimdal. Use the
"server_keytab" option to point to the keytab.
3. The "pkg-config" system can now be used when building Exim to reference
cflags and library information for lookups and authenticators, rather
than having to update "CFLAGS", "AUTH_LIBS", "LOOKUP_INCLUDE" and
"LOOKUP_LIBS" directly. Similarly for handling the TLS library support
without adjusting "TLS_INCLUDE" and "TLS_LIBS".
In addition, setting PCRE_CONFIG=yes will query the pcre-config tool to
find the headers and libraries for PCRE.
4. New expansion variable $tls_bits.
5. New lookup type, "dbmjz". Key is an Exim list, the elements of which will
be joined together with ASCII NUL characters to construct the key to pass
into the DBM library. Can be used with gsasl to access sasldb2 files as
used by Cyrus SASL.
6. OpenSSL now supports TLS1.1 and TLS1.2 with OpenSSL 1.0.1.
Avoid release 1.0.1a if you can. Note that the default value of
"openssl_options" is no longer "+dont_insert_empty_fragments", as that
increased susceptibility to attack. This may still have interoperability
implications for very old clients (see version 4.31 change 37) but
administrators can choose to make the trade-off themselves and restore
compatibility at the cost of session security.
7. Use of the new expansion variable $tls_sni in the main configuration option
tls_certificate will cause Exim to re-expand the option, if the client
sends the TLS Server Name Indication extension, to permit choosing a
different certificate; tls_privatekey will also be re-expanded. You must
still set these options to expand to valid files when $tls_sni is not set.
The SMTP Transport has gained the option tls_sni, which will set a hostname
for outbound TLS sessions, and set $tls_sni too.
A new log_selector, +tls_sni, has been added, to log received SNI values
for Exim as a server.
8. The existing "accept_8bitmime" option now defaults to true. This means
that Exim is deliberately not strictly RFC compliant. We're following
Dan Bernstein's advice in http://cr.yp.to/smtp/8bitmime.html by default.
Those who disagree, or know that they are talking to mail servers that,
even today, are not 8-bit clean, need to turn off this option.
9. Exim can now be started with -bw (with an optional timeout, given as
-bw<timespec>). With this, stdin at startup is a socket that is
already listening for connections. This has a more modern name of
"socket activation", but forcing the activated socket to fd 0. We're
interested in adding more support for modern variants.
10. ${eval } now uses 64-bit values on supporting platforms. A new "G" suffix
for numbers indicates multiplication by 1024^3.
11. The GnuTLS support has been revamped; the three options gnutls_require_kx,
gnutls_require_mac & gnutls_require_protocols are no longer supported.
tls_require_ciphers is now parsed by gnutls_priority_init(3) as a priority
string, documentation for which is at:
http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html
SNI support has been added to Exim's GnuTLS integration too.
For sufficiently recent GnuTLS libraries, ${randint:..} will now use
gnutls_rnd(), asking for GNUTLS_RND_NONCE level randomness.
12. With OpenSSL, if built with EXPERIMENTAL_OCSP, a new option tls_ocsp_file
is now available. If the contents of the file are valid, then Exim will
send that back in response to a TLS status request; this is OCSP Stapling.
Exim will not maintain the contents of the file in any way: administrators
are responsible for ensuring that it is up-to-date.
13. ${lookup dnsdb{ }} supports now SPF record types. They are handled
identically to TXT record lookups.
14. New expansion variable $tod_epoch_l for higher-precision time.
15. New global option tls_dh_max_bits, defaulting to current value of NSS
hard-coded limit of DH ephemeral bits, to fix interop problems caused by
GnuTLS 2.12 library recommending a bit count higher than NSS supports.
16. tls_dhparam now used by both OpenSSL and GnuTLS, can be path or identifier.
Option can now be a path or an identifier for a standard prime.
If unset, we use the DH prime from section 2.2 of RFC 5114, "ike23".
Set to "historic" to get the old GnuTLS behaviour of auto-generated DH
primes.
17. SSLv2 now disabled by default in OpenSSL. (Never supported by GnuTLS).
Use "openssl_options -no_sslv2" to re-enable support, if your OpenSSL
install was not built with OPENSSL_NO_SSL2 ("no-ssl2").

1. In addition to the existing LDAP and LDAP/SSL ("ldaps") support, there
is now LDAP/TLS support, given sufficiently modern OpenLDAP client
libraries. The following global options have been added in support of
this: ldap_ca_cert_dir, ldap_ca_cert_file, ldap_cert_file, ldap_cert_key,
ldap_cipher_suite, ldap_require_cert, ldap_start_tls.
2. The pipe transport now takes a boolean option, "freeze_signal", default
false. When true, if the external delivery command exits on a signal then
Exim will freeze the message in the queue, instead of generating a bounce.
3. Log filenames may now use %M as an escape, instead of %D (still available).
The %M pattern expands to yyyymm, providing month-level resolution.
4. The $message_linecount variable is now updated for the maildir_tag option,
in the same way as $message_size, to reflect the real number of lines,
including any header additions or removals from transport.
5. When contacting a pool of SpamAssassin servers configured in spamd_address,
Exim now selects entries randomly, to better scale in a cluster setup.

* Failure to get a lock on a hints database can have serious
consequences so log it to the panic log.
* Log LMTP confirmation messages in the same way as SMTP,
controlled using the smtp_confirmation log selector.

Avoid GNU Makefile-isms, let Exim continue to build on BSD.
Handle per-OS dynamic-module compilation flags.
* Let /dev/null have normal permissions.
The 4.73 fixes were a little too stringent and complained about the
permissions on /dev/null. Exempt it from some checks.
* Report version information for many libraries, including
Exim version information for dynamically loaded libraries. Created
version.h, now support a version extension string for distributors
who patch heavily. Dynamic module ABI change.
* CVE-2011-0017 - check return value of setuid/setgid. This is a
privilege escalation vulnerability whereby the Exim run-time user
can cause root to append content of the attacker's choosing to
arbitrary files.
* Bugzilla 1041: merged DCC maintainer's fixes for return code.
* Bugzilla 1071: fix delivery logging with untrusted macros.
If dropping privileges for untrusted macros, we disabled normal logging
on the basis that it would fail; for the Exim run-time user, this is not
the case, and it resulted in successful deliveries going unlogged.

* Date: & Message-Id: revert to normally being appended to a message,
only prepend for the Resent-* case. Fixes regression introduced in
Exim 4.70 by NM/22 for Bugzilla 607.

without a peer certificate, leading to a segfault because of an
assumption that peers always have certificates. Be a little more paranoid.

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.
