File Release Notes and Changelog

Release Name: 4.4.0

Notes:
Download: http://www.courier-mta.org/download.php#imap

Changes:

* Optimizations to IMAP keywords. A trade-off with concurrency: faster speed 
in exchange for a race condition if two concurrent sessions attempt to 
update keywords on the same message -- the last one wins.

* Add a POP3 login timeout.

* Fix parsing of backslashes in address fields.

* Implement SSL certificate based authentication.

* Fix minor issues with SSL/TLS session caching


Changes:

2008-07-11  Mr. Sam  <mrsam@courier-mta.com>

	* maildir/maildirquota.sgml: Update descriptions of maildir quotas.

2008-06-29  Mr. Sam  <mrsam@courier-mta.com>

	* pop3login.c (starttls): Use the couriertls library to invoke
	couriertls, instead of doing it ourselves. SASL authentication did
	not correctly handle the special case of "=" passed as the initial
	response to indicate an empty initial response. Switch to the new
	auth_sasl_ex() API.

	* pop3dcapa.c (pop3_externalauth): Check the environment variables
	for subject fields set by couriertls. Advertise the AUTH EXTERNAL
	capability, if they are set.

	* imaplogin.c (starttls): Use the couriertls library to invoke
	couriertls, instead of doing it ourselves.

	* capability.c (imap_externalauth): Check the environment variables
	for subject fields set by couriertls. Advertise the AUTH=EXTERNAL
	capability, if they are set.

	* authenticate_auth.c (authenticate): SASL authentication did not
	correctly handle the special case of "=" passed as the initial response
	to indicate an empty initial response. Switch to the new auth_sasl_ex()
	API.

	* tcpd/libcouriergnutls.c (oid_name_list): Rename "email" to
	"emailAddress", for compatibility with OpenSSL.

	* tcpd/libcouriergnutls.c (verify_client): Check for the required
	certificate occured in the wrong spot.

	* tcpd/libcouriergnutls.c (tls_connect): Add call to
	gnutls_certificate_set_subject() to actually request the client cert.

	* tcpd/libcouriergnutls.c (tls_certificate_verified): Return an
	indication if the peer's certificate is good.

	* tcpd/libcouriertls.c (tls_certificate_verified): Ditto. Minor bug
	fixes.

	* tcpd/starttls.c (dump_to_fp): Parse Subject: header dumped by
	couriertls, export it in environment variables.

	* tcpd/tlsclient.c (couriertls_get_subject): Retrieve individual
	Subject: fields.

	* tcpd/tlsclient.c (couriertls_export_subject_environment): Export
	parsed Subject: fields to the environment.

2008-06-21  Mr. Sam  <mrsam@courier-mta.com>

	* Optimize IMAP keyword implementation. Faster results in exchange
	for a concurrency tradeoff if two concurrent sessions attempt to
	update keywords for the same message at the same time -- only one will
	win.

2008-06-13  Mr. Sam  <mrsam@courier-mta.com>

	* rfc822_getaddr.c: Backslashed special characters in address names
	weren't being dequoted correctly by rfc822_getname() and
	rfc822_getname_orlist().

2008-05-11  Mr. Sam  <mrsam@courier-mta.com>

	* pop3login.c (main): Add a timeout to the POP3 login stage

2008-05-08  Bernd Wurst <bernd@bwurst.org>

2008-05-08  Mr. Sam  <mrsam@courier-mta.com>

	* bdbobj/Makefile.am: same patch. Also, clean up the rest of the
	makefiles.

2008-05-04  Kouhei Sutou <kou@cozmixng.org>

	* imapd.rc.in, pop3d.rc.in: Fix SSL initialization
