HISTORY

	mailbox_transport_maps, mailbox_command_maps or
	fallback_transport_maps, the local delivery agent did not
	log the problem before deferring mail, and produced no defer
	logfile record. Files: local/mailbox.c, local/unknown.c.

20120130

	Bugfix (introduced: Postfix 2.3): the trace service did not
	distinguish between DSN SUCCESS notifications for a non-bounce
	or a bounce message, and replied to mail from <>. This code
	pre-dates DSN support and should have been updated when it
	was re-purposed to handle DSN SUCCESS notifications.  Problem
	reported by Sabahattin Gucukoglu.  File:
	bounce/bounce_trace_service.c.

20120202

	Bugfix (introduced: Postfix 2.3): the "change header" milter
	request could replace the wrong header. A long header name
	could match a shorter one, because a length check was done
	on the wrong string.  Reported by Vladimir Vassiliev.  File:
	cleanup/cleanup_milter.c.

20120214

	Bugfix (introduced: Postfix 2.4): extraneous null assignment
	caused core dump when postlog emitted the "usage" message.
	Reported by Kant (fnord.hammer). File: postlog/postlog.c.

20120401

	Bitrot: shut up useless warnings about Cyrus SASL call-back
	function pointer type mis-matches. Files: xsasl/xsasl_cyrus.h,
	xsasl/xsasl_cyrus_server.c, xsasl/xsasl_client.c.

20120422

	Bit-rot: OpenSSL 1.0.1 introduces new protocols. Update the
	known TLS protocol list so that protocols can be turned off
	selectively to work around implementation bugs.  Based on
	a patch by Victor Duchovni.  Files: proto/TLS_README.html,
	proto/postconf.proto, tls/tls.h, tls/tls_misc.c, tls/tls_client.c,
	tls/tls_server.c.

20120425

	Workaround: bugs in 10-year old gcc versions break compilation
	with #ifdef inside a macro invocation (NOT: definition).
	Files: tls/tls.h, tls/tls_client.c, tls/tls_server.c.

20120517

	Workaround: to avoid crashes when the OpenSSL library is
	updated without "postfix reload", the Postfix TLS session
	cache ID now includes the OpenSSL library version number.
	Note: this problem cannot be fixed in tlsmgr(8). Code by
	Victor Duchovni. Files: tls/tls_server.c, tls_client.c.

20120520

	Bugfix (introduced Postfix 2.4): the event_drain() function
	was comparing bitmasks incorrectly causing the program to
	always wait for the full time limit. This error affected
	the unused postkick command, but only after s/fifo/unix/
	in master.cf.  File: util/events.c.

	Cleanup: laptop users have always been able to avoid
	unnecessary disk spin-up by doing s/fifo/unix/ in master.cf
	(this is currently not supported on Solaris systems).
	However, to make this work reliably, the "postqueue -f"
	command must wait until its requests have reached the pickup
	and qmgr servers before closing the UNIX-domain request
	sockets.  Files: postqueue/postqueue.c, postqueue/Makefile.in.

20120702

	Bugfix (introduced: 19990127): the BIFF client leaked an
	unprivileged UDP socket. Fix by Jaroslav Skarvada.  File:
	local/biff_notify.c.

20120730

	Bugfix (introduced: 20000314): AUTH is not allowed after
	MAIL. Timo Sirainen.  File: smtpd/smtpd_sasl_proto.c.

20121010

	Bugfix (introduced: Postfix 2.5): memory leak in program
	initialization. Reported by Coverity. File: tls/tls_misc.c.

	Bugfix (introduced: Postfix 2.3): memory leak in the unused
	oqmgr program. Reported by Coverity. File: oqmgr/qmgr_message.c.

20121013

	Cleanup: to compute the LDAP connection cache lookup key,
	join the numeric fields with null, just like string fields.
	Viktor Dukhovni. File: global/dict_ldap.c.

20121029

	Workaround: strip datalink suffix from IPv6 addresses
	returned by the system getaddrinfo() routine.  Such suffixes
	mess up the default mynetworks value, host name/address
	verification and possibly more.  File: util/myaddrinfo.c.

20130131

	Bugfix: the local(8) delivery agent dereferenced a null
	pointer while delivering to null command (for example, "|"
	in a .forward file).  Reported by Gilles Chehade.

20130203

	Bugfix: the 20121010 fix for tls_misc.c was documented but
	not included.

20130403

	Bugfix (introduced: Postfix 2.3): don't reuse TCP connections
	when smtp_tls_policy_maps is specified. Victor Duchovni.
	Found during Postfix 2.11 code maintenance.  File:
	smtp/smtp_reuse.c.

20130423

	Bugfix (introduced: Postfix 2.0): when myhostname is not
	listed in mydestination, the trivial-rewrite resolver may
	log "do not list <myhostname value> in both mydestination
	and <name of non-mydestination domain list>".  The fix is
	to re-resolve a domain-less address after adding $myhostname
	as the surrogate domain, so that it pops out with the right
	address-class label.  Problem reported by Quanah Gibson-Mount.
	File: trivial-rewrite/resolve.c.

20130425

	Bugfix (introduced: Postfix 2.2): don't reuse TCP connections
	when SASL authentication is enabled. SASL passwords may
	depend on the remote SMTP server hostname, but the Postfix
	<2.11 SMTP connection cache client does not distinguish
	between different hostnames that resolve to the same IP
	address.  Found during Postfix 2.11 code maintenance.  File:
	smtp/smtp_connect.c.

20130518

	Bugfix (introduced: 1997): memory leak after error while
	forwarding mail through the cleanup server. Viktor found
	one, Wietse eliminated the rest.  File: local/forward.c.

20130615

	TLS Interoperability: turn on SHA-2 digests by force.  This
	improves interoperability with clients and servers that
	deploy SHA-2 digests without the required support for
	TLSv1.2-style digest negotiation.  Based on patch by Viktor
	Dukhovni.  Files: tls/tls_client.c, tls/tls_server.c.

20130616

	Workaround: The Postfix SMTP server TLS session cache was
	broken because OpenSSL now enables session tickets by
	default, resulting in a different ticket encryption key for
	each smtpd(8) process.  The workaround turns off session
	tickets. In 2.11 we'll enable session tickets properly.
	Viktor Dukhovni. File: tls/tls_server.c.

20131026

	Future proofing: API changes in the PCRE library.  File:
	util/dict_pcre.c.

20131127

	Bugfix (introduced: 20090106): the postconf '-#' option
	erased prior options. File: postconf/postconf.c.

20131129

	Bugfix: Makefile example in MULTI_INSTANCE_README. Viktor
	Dukhovni. File: proto/MULTI_INSTANCE_README.html.

20131220

	Documentation: typo in SASL_README. Patrick Ben Koetter.
	File: proto/SASL_README.html.

20140104

	Bugfix: malformed error message. File: conf/post-install.
