> 8.13.3/8.13.3	2005/01/11
> 	Enhance handling of I/O errors, especially EOF, when STARTTLS
> 		is active.
> 	Make sure a connection is not reused after it has been closed
> 		due to a 421 error.  Problem found by Allan E Johannesen
> 		of Worcester Polytechnic Institute.
> 	Avoid triggering an assertion when sendmail is interrupted while
> 		closing a connection.  Problem found by Allan E Johannesen
> 		of Worcester Polytechnic Institute.
> 	Regression: a change in 8.13.2 caused sendmail not to try the
> 		next MX host (or FallbackMXhost if configured) when, at
> 		connection open, the current server returns a 4xy or 5xy
> 		SMTP reply code.  Problem noted by Mark Tranchant.

> 8.13.2/8.13.2	2004/12/15
> 	Do not split the first header even if it exceeds the internal
> 		buffer size.  Previously a part of such a header would
> 		end up in the body of the message.  Problem noted by
> 		Simple Nomad of BindView.
> 	Do not complain about "cataddr: string too long" when checking
> 		headers that do not contain RFC 2822 addresses.
> 		Problem noted by Rich Graves of Brandeis University.
> 	If a server returns a 421 reply to the RSET command between
> 		message deliveries, do not attempt to deliver any more
> 		messages on that connection.  This prevents bogus "Bad
> 		file number" recipient status.  Problem noted by
> 		Allan E Johannesen of Worcester Polytechnic Institute.
> 	Allow trailing white space in EHLO command as recommended by RFC
> 		2821.  Problem noted by Ralph Santagato of SBC Services.
> 	Deal with clients which use AUTH but negotiate a smaller buffer size
> 		for data exchanges than the value used by sendmail, e.g.,
> 		Cyrus IMAP lmtp server.  Based on patch by Jamie Clark.
> 	When passing ESMTP arguments for RCPT to a milter, do not cut
> 		them off at a comma.  Problem noted by Krzysztof Oledzki.
> 	Add more logging to milter change header functions to
> 		complement existing logging.  Based on patch from
> 		Gurusamy Sarathy of Active State.
> 	Include <lber.h> in include/sm/config.h when LDAPMAP is defined.
> 		Patch from Edgar Hoch of the University of Stuttgart.
> 	Fix DNS lookup if IPv6 is enabled when converting an IP address
> 		to a hostname for use with SASL.  Problem noted by Ken Jones;
> 		patch from Hajimu UMEMOTO.
> 	CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog
> 		mailer.  Patch from John Beck of Sun Microsystems.
> 	LIBMILTER: It was possible that xxfi_abort() was called after
> 		xxfi_eom() for a message if some timeouts were triggered.
> 		Patch from Alexey Kravchuk.
> 	LIBMILTER: Slightly rearrange mutex use in listener.c to allow
> 		different threads to call smfi_opensocket() and smfi_main().
> 		Patch from Jordan Ritter of Cloudmark.
> 	MAIL.LOCAL: Properly terminate MBDB before exiting.  Problem
> 		noted by Nelson Fung.
> 	MAIL.LOCAL: make strip-mail.local used a wrong path to access
> 		mail.local.  Problem noted by William Park.
> 	VACATION: Properly terminate MBDB before exiting.  Problem noted
> 		by Nelson Fung.
> 	Portability:
> 		Add support for DragonFly BSD.
