HISTORY

	Robustness: the SMTPD policy client now encodes the
	ccert_subject and ccert_issuer attributes as xtext.  Some
	characters are replaced by +XX, where XX is the two-digit
	hexadecimal code for the character value.  File:
	smtpd/smtpd_check.c.

	Bugfix: the Postfix SMTP client enforced Mandatory TLS only
	when talking to an ESMTP server; enforcement did not happen
	if Postfix could somehow be forced to send HELO instead of
	EHLO. Victor Duchovni.  File: src/smtp/smtp_proto.c.

20061203

	Bugfix (introduced with Postfix 2.2): with SMTP server
	tarpit delays of smtp_rset_timeout or larger, the SMTP
	client could get out of sync with the server while reusing
	a connection.  The symptoms were "recipient rejected .. in
	reply to DATA".  Fix by Victor Duchovni and Wietse.  File:
	smtp/smtp_proto.c, smtp/smtp_connect.c. Back-ported from
	Postfix 2.3.

	Safety: additional error tests to prevent connection reuse
	after timeout error. Files: lmtp/lmtp.c, smtp/smtp_connect.c.
	Back-ported from Postfix 2.3.

	Cleanup: misleading error message while discarding malformed
	input after queue file write error. File postdrop/postdrop.c.

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.

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.
