Feature changes in exim since 4.34 (bugfixes not listed):
Version 4.42
------------
1. The "personal" filter test is brought up-to-date with
recommendations from the Sieve specification: (a) The list
of non-personal From: addresses now includes "listserv",
"majordomo", and "*-request"; (b) If the message contains
any header line starting with "List=-" it is treated as
non-personal.
2. The Sieve functionality has been extended to support the
"copy" and "vacation" extensions, and comparison tests.
3. There is now an overall timeout for performing a callout
verification. It defaults to 4 times the callout timeout,
which applies to individual SMTP commands during the callout.
The overall timeout applies when there is more than one
host that can be tried. The timeout is checked before trying
the next host. This prevents very long delays if there are
a large number of hosts and all are timing out (e.g. when
the network connections are timing out). The value of the
overall timeout can be changed by specifying an additional
sub-option for "callout", called "maxwait". For example:
verify = sender/callout=5s,maxwait=20s
4. Changes to the "personal" filter test:
(1) The list of non-personal local parts in From: addresses
has been extended to include "listserv", "majordomo",
"*-request", and "owner-*", taken from the Sieve specification
recommendations.
(2) If the message contains any header line starting with
"List-" it is treated as non-personal.
(3) The test for "circular" in the Subject: header line
has been removed because it now seems ill-conceived.
5. The autoreply transport has a new option called never_mail.
This is an address list. If any run of the transport
creates a message with a recipient that matches any item
in the list, that recipient is quietly discarded. If all
recipients are discarded, no message is created.
Version 4.40
------------
The documentation is up-to-date for the 4.40 release. What
follows here is a brief list of the new features that have been
added since 4.30.
1. log_incoming_interface affects more log lines.
2. New ACL modifier "control = submission".
3. CONFIGURE_OWNER can be set at build time to define an
alternative owner for the configuration file, in addition
to root and exim.
4. Added expansion variables $body_zerocount, $recipient_data,
and $sender_data.
5. The time of last modification of the "new" subdirectory is
now used as the "mailbox time last read" when there is a
quota error for a maildir delivery.
6. The special item "+ignore_unknown" may now appear in host
lists.
7. The special domain-matching patterns @mx_any, @mx_primary,
and @mx_secondary can now be followed by "/ignore=<ip list>".
8. New expansion conditions: match_domain, match_address,
match_local_part, lt, lti, le, lei, gt, gti, ge, and new
expansion operators time_interval, eval10, and base62d.
9. New lookup type called "iplsearch".
10. New log selectors ident_timeout, tls_certificate_verified,
queue_time, deliver_time, outgoing_port, return_path_on_delivery.
11. New global options smtp_active_hostname and tls_require_ciphers.
12. Exinext has -C and -D options.
13. "domainlist_cache" forces caching of an apparently variable
list.
14. For compatibility with Sendmail, the command line option
-prval:sval is equivalent to -oMr rval -oMs sval.
15. New callout options use_sender and use_postmaster for use
when verifying recipients.
16. John Jetmore's "exipick" utility has been added to the
distribution.
17. The TLS code now supports CRLs.
18. The dnslookup router and the dnsdb lookup type now support
the use of SRV records.
19. The redirect router has a new option called qualify_domain.
20. exigrep's output now also includes lines that are not
related to any particular message, but which do match the
pattern.
21. New global option write_rejectlog. If it is set false, Exim
no longer writes anything to the reject log.
Changes in exim-exiscan since 4.34_22
27 - Changed algorithm of header_pos_middle to add headers
before the first header which is NOT Received: or
Resent-*:.
exim 4.42 ---------------------------------------------------
26 - Fixed header corruption when using header_pos_top.
(Thanks to Michael Deutschmann).
- Fixed headers being added before any Received-SPF:
header when using header_pos_middle (Thanks to
Michael Deutschmann).
- DrWeb malware support: Add flag to treat .eml file
as plain mail (Thanks to Alex Miller).
25 - Fixed include location of libspf2 headers.
- Added support for Kaspersky AV Version 5 (aveserver).
- Added expansion of av_scanner global variable
when it starts with a dollar sign. This is useful
for implementing multiple malware scanners.
- Added support for adding ACL headers at the beginning
and in the "middle" of the message header block.
(This is a preliminary solution, see comment in SPF
section of exiscan-acl-spec).
24 - Changed documentation to reflect libspf_alt->libspf2
name change.
- Upgraded included SRS patch to 0.3 (author Miles Wilton).
Also added a small doc chapter for SRS.
- Brightmail: put notes for users of new 6.x version in the
docs (search for "BMI6.x").
BMI Version 6 should work OK, an upgraded SDK is now on
Brightmail's download site.
exim 4.41 ----------------------------------------------------
23 - Added patch to support SRS in the redirect router, done
by Miles Wilton. Please check http://srs.mirtol.com/
for more information.
- Fixed the negation operator for SPF support. Thanks
to Michael Haardt for sending a patch.
- Increased buffer size for large SA reports (when using
custom SA rulesets).
- Increased buffer size for large BMI verdicts. Should now
handle large number of recipients gracefully.
