restart Postfix for this upgrade.

	Wietse

20050806

	Workaround: accept(2) fails with EPROTO when the client
	already disconnected (SunOS 5.5.1). File: sane_accept.c.

20050815

	Workaround: old Solaris compilers can't link an archive
	without globally visible symbols. File: tls/tls_misc.c.

20050922

	Bugfix: the *SQL clients did not uniformly choose the
	database host from the available pool of servers due to an
	off-by-one error, so that the "last" available server was
	not selected. Leandro Santi. Files: dict_mysql.c, dict_pgsql.c.

20050929

	Paranoia: don't ignore garbage in SMTP or LMTP server replies
	when ESMTP command pipelining is turned on. For example,
	after sending ".<CR><LF>QUIT<CR><LF>", Postfix could recognize
	the server's 2XX QUIT reply as a 2XX END-OF-DATA reply after
	garbage, causing mail to be lost. The SMTP and LMTP clients
	now report a remote protocol error and defer delivery.
	Files: smtp/smtp_chat.c, smtp/smtp_trouble.c, lmtp/lmtp_chat.c,
	lmtp/lmtp_trouble.c.

20051011

	Bugfix: raise the "policy violation" flag when a client
	request exceeds a concurrency or rate limit.  File:
	smtpd/smtpd.c.

	Bugfix (cut-and-paste error): don't reply with 421 (too
	many MAIL FROM or RCPT TO commands) when we aren't closing
	the connection.  File: smtpd/smtpd.c.

20051013

	Bugfix: don't do smtpd_end_of_data_restrictions after the
	transaction failed due to, e.g., a write error.  File:
	smtpd/smtpd.c.

	Cleanup: the SMTP server now enforces the message_size_limit
	even when the client did not send SIZE information with the
	MAIL FROM command.  This protects before-queue content
	filters against over-size messages.  File: smtpd/smtpd.c.

20051105

	Workaround: the next-hop logical destination information
	for connection caching was reset only after a good non-TLS
	connection, so that cached connections to non-TLS backup
	servers could suck away traffic from TLS primary servers
	(the Postfix SMTP client cannot cache an open TLS connection).
	Found during code review. Fixing this requires more change
	than is allowed in a stable release.  File: smtp/smtp_connect.c.

20051108

	Bugfix: two messages could get the same message ID due to
	a race condition. This time window was increased when queue
	file creation was postponed from MAIL FROM until the first
	accepted RCPT TO.  The window is closed again. Found by
	Victor. Files: global/mail_stream.c, global/mail_queue.c,
	cleanup/cleanup_message.c.

20051119

	Bugfix: the queue manager did not write a per-recipient
	defer logfile record when the delivery agent crashed after
	the initial handshake with the queue manager, and before
	reporting the delivery status to the queue manager.  Files:
	*qmgr/qmgr_deliver.c.

20051126

	Log warning when REDIRECT, FILTER, HOLD and DISCARD are
	used in smtpd_etrn_restrictions. File: smtpd/smtpd_check.c.

20051128

	Bugfix: moved code around from one place to another to make
	REDIRECT, FILTER, HOLD and DISCARD access(5) table actions
	work in smtpd_end_of_data_restrictions.  PREPEND will not
	be fixed; it must be specified before the message content
	is received.  Files: smtpd/smtpd.c, smtpd/smtpd_check.c,
	cleanup/cleanup_extracted.c, pickup/pickup.c.
