Log message:
Update mimedefang to version 2.52

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.

Log message:
RCD_SCRIPTS_EXAMPLEDIR is no longer customizable.
And always is defined as share/examples/rc.d
which was the default before.

This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.

This was discussed on tech-pkg in late January and late April.

Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests.

Log message:
The default location of the pkgsrc-installed rc.d scripts is now
under share/examples/rc.d. The variable name already was named
RCD_SCRIPTS_EXAMPLEDIR.

This is from ideas from Greg Woods and others.

Also bumped PKGREVISION for all packages using RCD_SCRIPTS mechanism
(as requested by wiz).

Log message:
Update to mimedefang 2.49

Changes: minor bug fixes.

Log message:
Update mimedefang to version 2.48

Changes in 2.48:
This is a bugfix release for 2.46 and 2.47, which contained several
embarrassing bugs.

Changes in 2.46:
This release has a mechanism for Perl slaves to report back their status
to the multiplexor. This allows you to see exactly what each scanning
slave is doing at a given point in time. This release also features
support for the "csav" virus-scanner from Command Software, and better
support for Trend Micro's command line scanner. The algorithm that
reconstructs MIME messages after modification is greatly improved and
avoids creating useless multipart containers with only a single sub-part.
A few smaller changes fix minor bugs and tighten up security.

Changes in 2.45:
The multiplexor has a new "-a" option to allow non-privileged users to
run a restricted set of status commands. "watch-mimedefang" has been
completely revamped and gives a lot of useful information about email
server load. It can monitor a remote server over an SSH tunnel. The
notification facility has two new messages, indicating a busy timeout and
the unexpected death of a Perl slave. There is a new set of RBL functions
that perform parallel DNS lookups to reduce latency. In addition, many
minor features have been added, bugs have been fixed, and documentation
has been cleaned up.

Log message:
Update mimedefang to version 2.44

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.

Log message:
Convert to buildlink3.

Log message:
mk/bsd.pkg.install.mk now automatically registers
the RCD_SCRIPTS rc.d script(s) to the PLIST.

This GENERATE_PLIST idea is part of Greg A. Woods'
PR #22954.

This helps when the RC_SCRIPTS are installed to
a different ${RCD_SCRIPTS_EXAMPLEDIR}. (Later,
the default RCD_SCRIPTS_EXAMPLEDIR will be changed
to be more clear that they are the examples.)

These patches also remove the etc/rc.d/ scripts from PLISTs
(of packages that use RCD_SCRIPTS). (This also removes
now unused references from openssh* makefiles. Note that
qmail package has not been changed yet.)

I have been doing automatic PLIST registration for RC_SCRIPTS
for over a year. Not all of these packages have been tested,
but many have been tested and used.

Somethings maybe to do:
- a few packages still manually install the rc.d scripts to
  hard-coded etc/rc.d. These need to be fixed.
- maybe  remove from mk/${OPSYS}.pkg.dist mtree specifications too.
