Update exim-exiscan to 4.43_28 from 4.42_27
Update exim-html to 4.40 from 4.30
exim-exiscan:
28 - Added F-Secure support, thanks to Johan Thelmen <jth@home.se>.
- Upgraded SRS support to libsrs_alt 0.5 via Miles
Wilton's patch.
- REMOVED exiscan-acl implementation of custom header
placement in favor of Philip Hazel's native implementation.
However, a new option option was added for it to
mimic the behaviour of the old header_pos_middle option.
Read section 10 of exiscan-acl-spec.txt.
exim:
1. Fixed a longstanding but relatively impotent bug: a long time ago, before
PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
Now it returns an integer. A number of calls were still expecting a T/F
return. Fortuitously, in all cases, the tests worked in OK situations,
which is the norm. However, things would have gone wrong on any write
failures on the smtp file descriptor. This function is used when sending
messages over SMTP and also when doing verify callouts.
2. When Exim is called to do synchronous delivery of a locally submitted
message (the -odf or -odi options), it no longer closes stderr before doing
the delivery.
3. Implemented the mua_wrapper option.
4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
5. Implemented the functions header_remove(), header_testname(),
header_add_at_position(), and receive_remove_recipient(), and exported them
to local_scan().
6. If an ACL "warn" statement specified the addition of headers, Exim already
inserted X-ACL-Warn: at the start if there was no header name. However, it
was not making this test for the second and subsequent header lines if
there were newlines in the string. This meant that an invalid header could
be inserted if Exim was badly configured.
7. Allow an ACL "warn" statement to add header lines at the start or after all
the Received: headers, as well as at the end.
8. Added the rcpt_4xx retry error code.
9. Added postmaster_mailfrom=xxx to callout verification option.
10. Added mailfrom=xxxx to the callout verification option, for verify=
header_sender only.
11. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
(they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
12. Inserted some casts to stop certain compilers warning when using pointer
differences as field lengths or precisions in printf-type calls (mostly
affecting debugging statements).
13. Added optional readline() support for -be (dynamically loaded).
14. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
same clock tick as a message's arrival, so that its received time was the
same as the "first fail" time on the retry record, and that message
remained on the queue past the ultimate address timeout, every queue runner
would try a delivery (because it was past the ultimate address timeout) but
after another failure, the ultimate address timeout, which should have then
bounced the address, did not kick in. This was a "< instead of <=" error;
in most cases the first failure would have been in the next clock tick
after the received time, and all would be well.
15. The special items beginning with @ in domain lists (e.g. @mx_any) were not
being recognized when the domain list was tested by the match_domain
condition in an expansion string.
16. Added the ${str2b64: operator.
17. Exim was always calling setrlimit() to set a large limit for the number of
processes, without checking whether the existing limit was already
adequate. (It did check for the limit on file descriptors.) Furthermore,
18. Imported PCRE 5.0.
19. Trivial typo in log message " temporarily refused connection" (the leading
space).
20. If the log selector return_path_on_delivery was set and an address was
redirected to /dev/null, the delivery process crashed because it assumed
that a return path would always be set for a "successful" delivery. In this
case, the whole delivery is bypassed as an optimization, and therefore no
return path is set.
21. Internal re-arrangement: the function for sending a challenge and reading
a response while authentication was assuming a zero-terminated challenge
string. It's now changed to take a pointer and a length, to allow for
binary data in such strings.
22. Added the cyrus_sasl authenticator (code supplied by MBM).
23. Exim was not respecting finduser_retries when seeking the login of the
uid under which it was called; it was always trying 10 times. (The default
setting of finduser_retries is zero.) Also, it was sleeping after the final
failure, which is pointless.
24. Implemented tls_on_connect_ports.
25. Implemented acl_smtp_predata.
26. If the domain in control=submission is set empty, Exim assumes that the
authenticated id is a complete email address when it generates From: or
Sender: header lines.
27. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
chown and chgrp in /bin and hostname in /usr/bin.
28. Exim was keeping the "process log" file open after each use, just as it
does for the main log. This opens the possibility of it remaining open for
long periods when the USR1 signal hits a daemon. Occasional processlog
errors were reported, that could have been caused by this. Anyway, it seems
much more sensible not to leave this file open at all, so that is what now
happens.
29. The long-running daemon process does not normally write to the log once it
has entered its main loop, and it closes the log before doing so. This is
so that log files can straightforwardly be renamed and moved. However,
there are a couple of unusual error situations where the daemon does write
log entries, and I had neglected to close the log afterwards.
30. The text of an SMTP error response that was received during a remote
delivery was being truncated at 512 bytes. This is too short for some of
the long messages that one sometimes sees. I've increased the limit to
1024.
31. It is now possible to make retry rules that apply only when a message has a
specific sender, in particular, an empty sender.
32. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
it possible to be selective about when SMTP synchronization is enforced.
33. Added "control = caseful_local_part" and "control = "caselower_local_part".
32. Implemented hosts_connection_nolog.
33. Added an ACL for QUIT.
34. Setting "delay_warning=" to disable warnings was not working; it gave a
syntax error.
35. Added mailbox_size and mailbox_filecount to appendfile.
36. Added control = no_multiline_responses to ACLs.
37. There was a bug in the logic of the code that waits for the clock to tick
in the case where the clock went backwards by a substantial amount such
that the microsecond fraction of "now" was more than the microsecond
fraction of "then" (but the whole seconds number was less).
38. Added support for the libradius Radius client library this is found on
FreeBSD (previously only the radiusclient library was supported).
