+ChangeLog for Dean Strik's IPv6 patch for Postfix. The patch is based on
+PLD's patch, which in turn seems to be based on KAME's. For more information:

+
+---------------------------------------------------------------------
+
+Version 1.25	Postfix release 2.1.3
+		Postfix release 2.0.20
+		Postfix snapshot 2.2-20040616
+
+	Bugfix: Misplaced myfree() caused a small memory leak. Reported
+	by Christian von Roques.
+	File: util/match_ops.c
+
+	Removed the colon (:) from the characters XFORWARD replaces by
+	a question mark (IPv6 addresses looked like 2001?610?1108?5010??1
+	in logging). Reported by Philipp Morger.
+	File: smtpd/smtpd.c
+
+Version 1.24	Postfix release 2.1.1
+		Postfix release 2.0.20
+		Postfix snapshot 2.0.19-20040312
+		Postfix snapshot 2.2-20040504
+
+	Bugfix: Prefixlen non-null host portion validation (in CIDR maps
+	for example) yielded incorrect results sometimes because signed
+	arithmetic was used instead of unsigned.
+	File: util/match_ops.c
+
+	Patch correction: The TLS+IPv6 patch for Postfix 2.1.0 missed
+	the master.cf update (used for new installations). Added it
+	back.
+
+Version 1.23	Postfix release 2.1.0
+		Postfix release 2.0.20
+		Postfix snapshot 2.0.19-20040312
+
+	Patch fixes: Several code fixes to make the patch compile
+	and work correctly when compiled without IPv6 support.
+
+	Bugfix (Solaris only?): address family length was not updated
+	which could cause client hostname validation errors.
+	File: smtpd/smtpd_peer.c
+
+	Portability: added support for Darwin 7.3+. This may need
+	some further testing.
+
+	Cleanup: Restructure and redocument interface address
+	retrieval functions. (This reduced the number of preprocessor
+	statements from 99 to 93 ;)
+	File: util/inet_addr_local.c
+
+	Cleanup: make several explicit casts to have compilers shut
+	their pie holes about uninteresting things.
+
+Version 1.22	Postfix release 2.0.19
+		Postfix snapshot 2.0.19-20040312
+
+	Feature: Support "inet_interfaces = IPv4:all" and
+	"inet_interfaces = IPv6:all", to restrict postfix to use
+	either IPv4-only or IPv6-only. A more complete implementation
+	will be part of a future patch. (Slightly modified) patch by
+	Michal Ludvig, SuSE.
+	Files: util/interfaces_to_af.[ch], util/inet_addr_local.c,
+	global/own_inet_addr.c, global/wildcard_inet_addr.[ch],
+	master/master_ent.ch
+
+	Bugfix: In Postfix snapshots, a #define was misplaced with
+	the effect that IPv6 subnets were not included in auto-
+	generated $mynetworks (i.e., mynetworks not defined in main.cf,
+	when also mynetworks_style=subnet) on Linux 2.x systems.
+	File: utils/sys_defs.h
+
+Version 1.21a	Postfix snapshots 2.0.18-2004{0122,0205,0209}
+				  2.0.19-20040312
+
+	TLS/snapshot version: Update TLS patch to 0.8.18-20040122.
+	Performed as a total repatch. 0.8.18 is cleaner with tls_*
+	variables if TLS is not actually compiled in.
+
+Version 1.21	Postfix releases 2.0.18 - 2.0.19
+		Postfix snapshot 2.0.16-20031231
+
+	Bugfix: The SMTP client could fail to setup a connection,
+	erroring with a bogus "getaddrinfo(...): hostname nor servname
+	provided" warning, because the wrong address was selected.
+	File: smtp/smtp_connect.c
+
+	Safety: in dynamically growing data structures, update the
+	length info after (instead of before) updating the data size.
+	File: util/inet_addr_list.c
+
+Version 1.20	Postfix release 2.0.16
+		Postfix snapshot 2.0.16-20031207
+
+	Bugfix: The SMTP client would abort when binding to specific
+	IPv6 addresses.
+	File: smtp/smtp_connect.c
+
+	Synchronisation/bugfix: LMTP source address binding is identical
+	to the SMTP source binding setup, avoiding the need for
+	lmtp_bind_address(6) if inet_interfaces is set to a single
+	host for an address family.
+	File: lmtp/lmtp_connect.c
+
+Version 1.19	Postfix release 2.0.16
+		Postfix snapshot 2.0.16-20031207
+
+	Bugfix: Synchronisation of TLS patches in snapshots of 1.18[ab]
+	was not complete, causing a crash of smtpd if used with the new
+	proxy agent.
+	File: smtpd/smtpd.c
+
+	Bugfix: SMTP source address binding based on a single hostname
+	in inet_interfaces did not work since the code counted IPv4 and
+	IPv6 addresses instead of only the used address family. Fixed,
+	thereby no longer requiring exact specification of
+	smtp_bind_address(6) in this case.
+	File: smtp/smtp_connect.c
+
+	Bugfix: The QMQP sink server did not compile correctly. This
+	program, part of smtpstone tools, is not compiled or installed
+	by default.
+	File: smtpstone/qmqp-sink.c
+
+	Bugfix: NI_WITHSCOPEID was not correctly defined everywhere,
+	which could result in EAI_BADFLAGS. Changed location of
+	definition to correct it.
+	Files: util/sys_defs.h, util/inet_addr_list.h
+
+Version 1.18b	Postfix snapshot 2.0.16-20030921
+
+	IPv6 support: Added IPv6-enabled code to the new snapshot
+	check_*_{ns,mx}_access restrictions.
+	File: smtpd/smtpd_check.c
+
+Version 1.18a	Postfix release 2.0.16
+
+	Update (TLS patches): Updated Lutz Jaenicke's TLS patch to
+	version 0.8.16. See pfixtls/ChangeLog for details.
+	Diff contributed by Tuomo Soini.
+
+	The TLS+IPv6 patch now contains the original TLS patch
+	documentation from Lutz Jaenicke.
+
+Version 1.18	Postfix releases 2.0.14 - 2.0.15
+		Postfix snapshot 2.0.14-20030812
+
+	Bugfix: Perform actual hostname verification in the SMTP
+	and QMTP servers. This was never supported in the IPv6
+	patch. Reported by Wolfgang S. Rupprecht.
+	Files: smtpd/smtpd_peer.c, qmqpd/qmqpd_peer.c
+
+	IPv6 address ranges using address/prefixlength (e.g. in
+	mynetworks and access maps) should be written as
+	[ipv6:addr:ess]/plen (e.g. [fec0:10:20::]/48). The old
+	supported syntax, [ipv6:addr:ess/plen] is deprecated and
+	support will be removed in a later version.
+	Thanks to Dr. Peter Bieringer and Pekka Savola for discussion.
+	Files: util/match_ops.c, global/mynetworks.c
+
+	Explicitly prefer IPv6 over IPv4 addresses when delivering
+	to a host when MX lookups are disabled when SMTP address
+	randomization is on (default).
+	File: smtp/smtp_addr.c
+
+	Compliance: write IPv6 address literals in mail headers 
+	as [IPv6:addr] instead of [addr] as per RFC 2821:4.1.3
+	tagging requirement, for example [IPv6:fec0:10:20::1].
+	Pointed out by Dr. Peter Bieringer.
+	Files: smtpd/smtpd{,_peer,_state}.c, smtpd/smtpd.h
+
+Version 1.17	Postfix release 2.0.13, 2.0.14
+		Postfix snapshot 2.0.13-20030706, 2.0.14-20030812
+
+	Bugfix: Two memory allocation/deallocation bugs were
+	introduced in patch 1.16. The impact of these bugs could
+	be 'arbitrary' memory corruption.
+	File: util/match_ops.c
+
+Version 1.16	Postfix release 2.0.13
+		Postfix snapshot 2.0.13-20030706
+
+	Cleanup: rewrote match_ops.c. This rewrite is partly based on
+	patch by Takahiro Igarashi. The rewrite enables some better
+	handling of scoped addresses, and drops all GPL code from the
+	patch, easying license considerations. Also, allowed for
+	use of this code by the CIDR maps.
+	Files: util/match_ops.[ch]
+
+	Bugfix: correctly relay for scoped unicast addresses when
+	applicable. Until now, while Postfix was able to recognize
+	scoped addresses, it was not able to see e.g. fe80::10%fxp0
+	as local in mynetworks validation.  KAME-only code.
+	(I've never heard of people using scoped addresses (think
+	link-local addresses) for mail relaying though...)
+	Files: util/inet_addr_list.[ch]
+
+	Feature (snapshot only): rewrote CIDR maps code to support
+	IPv6 addresses, using new match_ops code. Allow the use
+	of [::/0] since it allows one to easily disable further
+	checks for IPv6 addresses.
+	File: util/dict_cidr.c
+
+	Consistency: require IPv6 addresses in inet_interfaces to
+	be enclosed in square brackets.
+	File: util/inet_addr_host.c
+
+	Bugfix: (Linux2-only) A #define was misspelled. This could
+	lead to Postfix being unable to read the system's local IPv6
+	addresses (e.g. when using inet_interfaces).
+	Spotted by Jochen Friedrich.
+	File: util/sys_defs.h
+
+	Cleanup: require non-null host portion in CIDR /
+	prefixlength notations for IPv6 (was IPv4-only).
+
+Version 1.15a	Postfix release 2.0.13
+
+	Update (TLS patches): Updated Lutz Jaenicke's TLS patch
+	to version 0.8.15. This version introduces new options
+	for managing SASL mechanisms. More information at:
+	http://www.aet.tu-cottbus.de/personen/jaenicke/pfixtls/
+	Diff contributed by Tuomo Soini.
+
+Version 1.15	Postfix release 2.0.12, 2.0.13
+		Postfix snapshot 2.0.12-20030621
+
+	Bugfix (TLS-snapshots only): a change in Postfix snapshot
+	2.0.11-20030609 broke initialisation of TLS in smtpd,
+	causing TLS to both be unadvertised and unaccepted.
+	This was fixed again by reordering initialisation.
+	File: smtpd/smtpd.c
+
+	Update (TLS patches): Updated Lutz Jaenicke's TLS patch
+	to version 0.8.14. This version introduces a few fixes and
+	uses USE_SSL instead of HAS_SSL. More information at:
+	http://www.aet.tu-cottbus.de/personen/jaenicke/pfixtls/
+	Diff contributed by Tuomo Soini.
+
+	Bugfix (Postfix releases only - this was already added to
+	the snapshots in patch 1.14). KAME derived systems only.
+	Correctly decode scoped addresses, including network
+	interface specifiers.
+	File: util/inet_addr_local.c
+
+Version 1.14	Postfix releases 2.0.9, 2.0.10, 2.0.11, 2.0.12
+		Postfix snapshots 2.0.9-20030424, 2.0.10-20030521,
+				  2.0.11-20030609, 2.0.12-20030611
+
+	Patch change: made the patch available as an IPv6-only
+	patch (i.e., without the TLS code). This on popular
+	request by users and packagers.
+	A TLS+IPv6 version is still available of course.
+
+	Bugfix: correctly decode scoped addresses from now on
+	(KAME derived systems only). I think the original code
+	was written by Itojun, so I'm rather puzzled that it
+	didn't work...
+	File: util/inet_addr_local.c
+
+	Bugfix/portability: Recent KAME snapshots return both
+	TCP and SCTP address information on getaddrinfo() if
+	no protocol was specified. This causes the socket counts
+	to be wrong, confusing child processes.
+	Merged patch by JINMEI Tatuya of KAME to fix this.
+	Files: master/master.h, master/master_{ent,conf}.[ch],
+		util/inet_listen.c
+
+	Documentation: added an IPV6_README file to the patch.
+	This file contains the primary documentation. Also,
+	added a sample-ipv6.cf to describe the (currently few)
+	IPv6 related main.cf parameters.
+
+	Bugfix: the netmask structures for the *unsupported*
+	platforms (boldly assume /64) were added to the wrong
+	list (addresses instead of masks). This bug did not affect
+	any supported platform though.
+	File: util/inet_addr_local.c
+
+	Portability: added support for HP/Compaq Tru64Unix V5.1
+	and later. (compiled with CompaqCC only).
+	Thanks to Sten Spans for providing root access to an
+	IPv6-connected Tru64 testing machine.
+
+Version 1.13	Postfix releases 2.0.4 - 2.0.9
+		Postfix snapshots 2.0.3-20030126 - 2.0.7-20030319
+
+	Bugfix: Due to a missing storage pointer, DNS lookup
+	results in the permit_mx_backups code were not processed,
+	and smtpd would likely crash.
+	Thanks to Wouter de Jong for reporting the crashes.
+	File: smtpd/smtpd_check.c
+
+	Incompatible change: The addresses given to the parameters
+	smtp_bind_address6 and lmtp_bind_address6 now need to be
+	enclosed in square brackets for consistency.
+	Files: [ls]mtp/[ls]mtp_connect.c
+
+Version 1.12	Postfix releases 2.0.2, 2.0.3
+		Postfix snapshots 2.0.2-20030115, 2.0.3-20030126
+
+	Bugfix/workaround (Solaris): A simplified comparison
+	function for Solaris' qsort() function, would result
+	in corruption of network addresses in the SMTP client.
+	Fixed. Reported with possible fix by Edvard Tuinder.
+	File: smtp/smtp_addr.c
+
+Version 1.11	Postfix releases 2.0.0.x, 2.0.1, 2.0.2
+		Postfix snapshots 2.0.0-20030105, 2.0.1-20030112
+			2.0.2-20030115
+
+	Bugfix (Solaris): Properly initialize lifconf structure
+	when requesting host interface addresses. If you get
+	warnings about SIOCGLIFCONF with earlier versions,
+	please upgrade.
+	File: util/inet_addr_local.c
+
+	Patch fix: fixed compilation errors in case the patch is
+	applied but built without IPv6 support (i.e., on unsupported
+	platforms).
+
+Version 1.10	Postfix snapshots 1.1.12-200212{19,21}
+		Postfix releases 2.0.0, 2.0.0.{1,2}
+		Postfix snapshots 2.0.0-20021223 - 2.0.0-20030101
+
+	'Bugfix': don't show spurious warnings on Linux systems
+	about missing /proc/net/if_inet6 unless verbose mode
+	is enabled.
+	File: util/inet_addr_local.c
+
+	Bugfix: If unable to create a socket for a specific adress
+	in the SMTP client (e.g., when trying to create an IPv6
+	connection while the local host has no configured IPv6
+	addresses), then stop the attempt.
+	File: smtp/smtp_connect.c
+
+	Small bugfix: never query DNS for <localpart@[domain.tld]>.
+	This syntax now correctly generates an error immediately.
+	File: global/resolve_local.c
+
+	Updated TLS patch to 0.8.12-1.1.12-20021219-0.9.6h, fixing
+	a bug with "sendmail -bs".
+
+Version 1.9	Postfix version 1.1.11-20021115
+		Postfix version 1.1.12-2002{1124,1209-1213}
+
+	Bugfix: with getifaddrs() code (*BSD, linux-USAGI), IPv4
+	netmasks were set to /32 effectively. Work around broken
+	netmask data structures (*BSD only perhaps).
+
+	Bugfix: same data corruption in another place created
+	entirely wrong IPv4 netmasks. Work around broken
+	SIOCGIFNETMASK structure.
+
+	New code was added for correct IPv6 netmasks. The original
+	code did not contain IPv6 netmask support at all!
+	For Solaris, use SIOCGLIF*; Linux: /proc/net/if_inet6.
+	Getifaddrs() support is used otherwise. This should cover
+	all supported systems. Other systems also work, prefix
+	length is always set to /64 then.
+
+	Since there are no classes (context: Class A, class B etc
+	networks) with IPv6, default to IPv6 subnet style if the
+	mynetworks style is 'class'. I recommend against this style
+	anyway.
+
+	Added support to display IPv6 nets mynetworks output.
+
+Version 1.8	Postfix version 1.1.11-200211{01,15}
+
+	An earlier author of the patch made a typo in the GAI_STRERROR()
+	macro, resulting in bogus error messages when checking for
+	PTR records. Fixed.
+
+	IPv4-mapped addresses in the smtpd are converted to true IPv4
+	addresses just after the connection has been made. This means
+	that all IPv4-mapped addresses are now logged as true IPv4
+	addresses. Hence beside RBL checks, also access maps now treat
+	IPv4-mapped addresses as native IPv4. Note that ::ffff:...
+	entries in your access tables will no longer work.
+
+	You can now specify IPv6 'parent' networks in your access maps,
+	e.g. to reject all mail from 3ffe:200:... nodes, add the line
+		3ffe:200	REJECT
+	Use of trailing colons is discouraged because postmap will
+	warn about it possibly being an alias...
+	NOTE: I'll soon obsolete this again in favor of the more
+	common address/len notation. This was just so trivial to add
+	that it didn't hurt and I needed it :)
+
+	For easy reference, the version of the TLS/IPv6 patch can be
+	dynamically queried using the  tls_ipv6_version  variable.
+	This gives the short version (like, "1.8").
+
+	The service bind address for 'inet' sockets in master.cf (e.g.,
+	smtpd), must be enclosed in square brackets '[..]' for IPv6
+	addresses. The old style (without brackets) still works but is
+	unsupported and may be removed in the future. Example
+	    [::1]:smtp inet n - n - - smtpd
+
+Version 1.7	Postfix version 1.1.11-20021029 - 1.1.11-20021101
+
+	Postfix' SMTP client performs randomization of MX addresses
+	when sending mail. This however could result in A records
+	being used before AAAA records. This has been corrected.
+
+	Note that from Postfix version 1.1.11-20021029 on, there is
+	a  proxy_interfaces  parameter. This has of course not been
+	ported to IPv6 addresses...
+
+Version 1.6	Postfix version 1.1.11-20020928
+
+	Added IPv6 support for backup_mx_networks feature; also the
+	behaviour when DNS lookups fail when checking whether the
+	local host is an MX for a domain conforms to the IPv4 case:
+	defer rather than allow.
+
+Version 1.5	Postfix version 1.1.11-20020917
+
+	I introduced two bugs when I rewrote my older LMTP IPv6 patch.
+	These bugs effectively rendered LMTP useless. Now fixed.
+	Bugs spotted by Kaj Niemi.
+
+	Now supports Solaris 8 and 9. Due to lack of testing equipment,
+	this has been only tested in production on Solaris 9, both
+	with gcc and the Sun Workshop Compiler.
+
+Version 1.4	Postfix version 1.1.11-20020822 - 1.1.11-20020917
+
+	OpenBSD (>=200003) and FreeBSD release 4 and up now use
+        getifaddrs(). This makes for cleaner code. The old code
+	seems to be bug-ridden anyway.
+
+	Got rid of some compiler warnings. Should be cleaner on
+	Alpha as well now. Thanks to Sten Spans for providing me
+	access to an Alpha running FreeBSD4.
+
+	Fixed an old bug in smtpd memory alloation if you compiled
+	without IPv6 support (the wrong buffer size was used. This
+	was harmless for IPv6-enabled compiles since the sizes were
+	equal then).
+
+	Added ChangeLog to the patch (as IPv6-ChangeLog) (this
+	was absent in 1.3 contrary to docs).
+
+Version 1.3	Postfix version 1.1.11-20020613 - 1.1.11-20020718
+
+	FYI: In postfix version 1.1.11-20020718, DNS lookups for
+	AAAA can be done natively. The code matches the code in
+	the patch (though the #ifdef changed from INET6 to T_AAAA).
+	This change causes the patch for 1.1.11-20020718 to be a
+	bit smaller.
+
+Version 1.2	Postfix version 1.1.11-20020613
+
+	Added IPv6 support for the LMTP client.
+
+	Added lmtp_bind_address and lmtp_bind_address6 parameters,
+	similar to those for smtp.
+
+	Added IPv6 support for the QMQP server.
+
+Version 1.1	Postfix version 1.1.11-20020602 - 1.1.11-20020613
+
+	Added parameter smtp_bind_address6. By using this parameter,
+	it is possible to bind to an IPv6 address, independently of
+	IPv4 address binding.
+
+	Lutz fixed a bug in his TLS patch regarding SASL. Incorporated.
+
+Version 1.0.x	Postfix version 1.1.8-20020505 - 1.1.11-20020602
+
+	Patch derived from PLD's IPv6 patch for Postfix, revision 1.10
+	which applied to early Postfix snapshots 1.1.x. Updated this
+	patch to apply to 1.1.8-20020505.
+
+	Added compile-time checks for SS_LEN. Some Linux installations,
+	and maybe other systems, do define SA_LEN, but not SS_LEN.
+
+	Several updates of postfix snapshots.
+
