Changes in 2.52
* mimedefang.pl.in (item_contains_virus_fprotd): Remove all references
to $` and $', which can SIGNIFICANTLY slow down Perl regexp matching.
* mimedefang.c(mfconnect): Do not call set_dsn from mfconnect, because
the Milter API specifies that you can't call smfi_setreply from the
connect callback.
* mimedefang-filter.5.in: Document the fact that filter_relay
cannot set the text of the SMTP reply code.
* mimedefang.pl: We don't detect and load Perl modules until
the detect_and_load_perl_modules() function is called.
*** NOTE INCOMPATIBILITY ***
You *MUST* call detect_and_load_perl_modules() inside your filter
before you can rely on the %Features hash being set correctly,
and before you can rely on SpamAssassin being loaded!!!
Changes in 2.51
Note: There was no public 2.50 release; the 2.50 version was a
private release that was available only with CanIt.
* Added "-q" option to mimedefang. This permits the multiplexor
to queue new incoming connections. It may make higher utilization
of slaves and improve throughput.
* ESMTP arguments in MAIL FROM: and RCPT TO: are now available
to the Perl filter. See the mimedefang-filter(5) man page for
details.
* Documentation fixes: We don't refer to non-multiplexor mode
any more, because that mode hasn't been available for ages.
* The "tick" facility has been enhanced to permit multiple tick
types. At any given instance, only one tick of a given type
can be active, but ticks of different types can be active at
the same time.
* Log a warning if a message has more than one Subject: header.
Changes in 2.44:
This release features support for two new Sendmail 8.13 features: the
SOCKETMAP map type, and Sendmail's built-in quarantine mechanism. There are
also some minor bugfixes and documentation cleanups, as well as a fix for a
memory leak with the embedded Perl interpreter on some platforms.
Changes in 2.43:
Various Perl functions can request the C code to delay before returning;
this permits tarpitting without tying up a Perl slave. The multiplexor has
an additional option to run a "tick" function on a periodic basis. There
are minor bugfixes and documentation improvements.
Changes in 2.42:
The multiplexor causes closelog() to avoid problems with embedded Perl
slaves. Support for SpamAssassin's upcoming 3.0.0 Perl API was added. A few
other small bugs were fixed.
Changes in 2.41:
This is a bugfix release only. The most important change is to stop the
action_quarantine_entire_message from sending out notifications each time
it is invoked. A few other minor bugs were fixed.
