20070501

	Safety: when IPv6 (or IPv4) is turned off, don't treat an
	IPv6 (or IPv4) connection from e.g. inetd as if it comes
	from localhost[127.0.0.1]. Files: smtpd/smtpd_peer.c,
	qmqpd/qmqpd_peer.c.

20070508

	Bugfix: Content-Transfer-Encoding: attribute values are
	case insensitive. File: src/cleanup/cleanup_message.c.

20070514

	Bugfix: mailbox_transport(_maps) and fallback_transport(_maps)
	were broken when used with the error(8) or discard(8)
	transports. Cause: insufficient documentation.  Files:
	error/error.c, discard/discard.c.

20070520

	Bugfix (problem introduced Postfix 2.3): when DSN support
	was introduced it broke "agressive" recipient duplicate
	elimination with "enable_original_recipient = no".  File:
	cleanup/cleanup_out_recipient.c.

20070529

	Bugfix (introduced Postfix 2.3): the sendmail/postdrop
	commands would hang when trying to submit a message larger
	than the per-message size limit. File: postdrop/postdrop.c.

20070530

	Sabotage the saboteur who insists on breaking Postfix by
	adding gethostbyname() calls that cause maildir delivery
	to fail when the machine name is not found in /etc/hosts,
	or that cause Postfix processes to hang when the network
	is down.

20070531

	Portability: Victor helpfully pointed out that change
	20070425 broke on non-IPv6 systems. Files: smtpd/smtpd_peer.c,
	qmqpd/qmqpd_peer.c.

20070722

	Cleanup: Milter client error handling, so that the (Postfix
	SMTP server's Milter client) does not get out of sync with
	Milter applications after the (cleanup server's Milter
	client) encounters some non-recoverable problem.  Files:
	milter/milter8.c, smtpd/smtpd.c.  Back-port from Postfix
	2.4/2.5.

20070729

	Performance: workaround for poor TCP performance on loopback
	(127.0.0.1) connections. Reported by Mark Martinec.  Files:
	util/vstream_tweak.c, milter/milter8.c, smtp/smtp_connect.c,
	smtpstone/*source.c. Back-port from Postfix 2.4/2.5.

20070730

	Bugfix: when a milter replied with ACCEPT at or before the
	first RCPT command, the cleanup server would apply the
	non_smtpd_milters setting as if the message was a local
	submission. Problem reported by Jukka Salmi. Also, the
	cleanup server would get out of sync with the milter when
	a milter replied with ACCEPT at the DATA command. Files:
	cleanup/cleanup_envelope.c, smtpd/smtpd.c, milter/milters.c.
	Back-port from Postfix 2.4/2.5.

20070911

	Bugfix (introduced Postfix 2.2.11): TLS client certificate
	with unparsable canonical name caused the SMTP server's
	policy client to allocate zero-length memory, triggering
	an assertion that it shouldn't do such things.  File:
	smtpd/smtpd_check.c. Back-port from Postfix 2.4/2.5.

20070917

	Workaround: the flush daemon forces an access time update
	for the per-destination logfile, to prevent an excessive
	rate of delivery attempts when the queue file system is
	mounted with "noatime".  File: flush/flush.c. Back-port
	from Postfix 2.4/2.5.

20071030

	Bugfix (introduced Postfix 2.3): Postfix mistakenly enforced
	the 64kbyte limit (for sending body parts TO Milter
	applications) also while receiving packets FROM Milter
	applications.  The limit is now at least 1GB.  File:
	milter/milter8.c.

20071202

	Bugfix (introduced Postfix 2.2): don't update the back-to-back
	delivery time stamp while deferring mail. File: *qmgr/qmgr_entry.c.

20071211

	Bugfix (introduced 19980315): the "write" equivalent of
	bugfix 20030104. File: util/vstream.c.

20071213

	Bugfix (introduced Postfix 2.3): the SMTP client never
	marked corrupt files as corrupt. Victor Duchovni. File:
	smtp/smtp_proto.c.

20071229

	Bugfix: the Milter client did not replace the Postfix-specific
	form for unknown host names by the Sendmail-specific form.
	File: milter/milter8.c.

20080104

	Workaround: minor change to the Dovecot AUTH request to
	prevent dovecot-auth memory wastage. Timo Sirainen.  File:
	xsasl/xsasl_dovecot_server.c.
