Upgraded Port: mail/dcc-dccd to 1.3.50

Changes in this release:

	o	Make "option forced-discard-nok" in /var/dcc/whiteclnt the default for
		dccm as well as dccifd in proxy mode.

	o	Add whiteclnt type of IP address entry "submit".
		It is intended to be applied to the IP addresses of SMTP submission
		clients such as web browsers that cannot tolerate 4yz temporary
		rejections of mail, but that cannot be trusted to not send spam.

	o	Let body and reputation checksum thresholds be set in the global and
		per-user whiteclnt files.  "Never" is a valid threshold and turns
		off rejections for a checksum.

	o	Overhaul proof of concept per-user whiteclnt CGI scripts to handle
		per-user checksum thresholds.

	o	Rationalize /var/dcc/libexec/dcc-stats-graph -tTITLE

	o	Fix bugs with -eNEVER and -Enever in dbclean.

	o	Add "submit" to "mx" and "mxdcc" values for IP addresses whiteclnt files
		to mark SMTP clients that are submitting new messages and that
		do not understand 4yz rejections for individual recipients.

	o	Fix dccifd crash on bogus long recipient names.

	o	/var/dcc/libexec/fetchblack is not as noisy when the sources of the
		public DCC server blacklist are down for long periods.

	o	Limit the database window to less than 2 GBytes on all 32-bit systems
		including Solaris.  Previous versions assumed that Solaris would
		do the right thing if it allowed large files.

	o	Fix bugs in the "skipping asking DCC server" mechanism that made it
		too forgiving.

	o	Remove the `dccd -t` thresholds in favor of simple constants.

	o	Dccm, dccifd, and dccproc now emit X-DCC headers for locally white-
		and blacklisted messages even when no DCC server responds.

	o	Automatically compensate for incompatibility in newer versions of
		rrdtool.

	o	Increase the computed limit on `dccm -j` by not dedicating two FDs
		to each thread for per-user log files but instead doing some locking.

	o	Fix memory leak in dccm and dccifd when DNSBLs (-B) are used.

	o	Improve performance on current UNIX-like systems that have madvise()
		with large DCC server databases.

	o	Mention the "incompatible whitelists" message in the FAQ.

	o	Do not greylist mail from SMTP submission clients marked by
		"submit IP" lines in /var/dcc/whiteclnt.

	o	Stop race with idle DNSBL helper processes.

	o	More adjustments to help deal with large databases.

	o	Change header checksums to ignore all instead of only some occurrences
		characters matching [<>'"]

	o	Dccm uses SMFIP_RCPT_REJ in sendmail 8.14 to detect dictionary attacks
		and adjust the DCC Reputation of attackers.

	o	Fix a very rare infinite loop in the MIME decoding code in DCC clients.

	o	Add "option log-subdirectory-{day,hour,minute}" to whiteclnt files
		to create per-user log files in subdirectories like the subdirectories
		used for /var/dcc/log with dccm, dccifd, and dccproc -l.

	o	Detect too-small file size resource limits in dccd and dbclean.

	o	Compile with -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64.

	o	Add dccm and dccifd -Bset:maxjobs=X.

	o	Fix printf(null) crash in dccifd acting as a proxy for CommuniGate.

	o	Remove support for external filters as part of the fix for the
		thundering herd problem in `dccm -B`.

	o	Check NS IP addresses in DNS blacklists (DNSBLs) before MX IP addresses
		for dccproc, dccifd, and dccm -B.

	o	Fix `dccm -tsubstitute...` problem.

	o	Significantly improve speed on large FreeBSD DCC servers.

	o	Make dbclean automatic -e/-E adjustments much more stable to
		significantly help DCC servers on Mondays and Tuesdays.

	o	Fix bad Body and missing Fuz1 and Fuz2 checksums for dccifd and dccm
		when previous messages had bad MIME encapsulation.

	o	Turn off automatic generation of 64-bit DCC servers.

	o	Change dbclean to use a dccd optimization and be faster on FreeBSD
		systems that have less that 4 GByte of RAM.

	o	Set the GID of dccifd, dccm, and dccproc log files and subdirectory
		to be the same as the parent directory if running as root and
		if necessary.

	o	Fix client random selection of public DCC servers.
		/var/dcc/blacklist also affects flooding peers.

	o	Implement FreeBSD specific rc.d startup script, as submitted by 
		Ken Menzel.
