There are a ton of proxying related improvements in this release. You
should now be able to do pretty much anything you want with Dovecot

This release also includes the initial version of dsync-based
replication. I'm already successfully using it for @dovecot.fi mails,
but it still has some problems. See
http://dovecot.org/list/dovecot/2012-March/064243.html for some details
how to configure it.

	+ Initial implementation of dsync-based replication. For now this
	  should be used only on non-critical systems.
	+ Proxying: POP3 now supports sending remote IP+port from proxy to
	  backend server via Dovecot-specific XCLIENT extension.
	+ Proxying: proxy_maybe=yes with host=<hostname> (instead of IP)
	  works now properly.
	+ Proxying: Added auth_proxy_self setting
	+ Proxying: Added proxy_always extra field (see wiki docs)
	+ Added director_username_hash setting to specify what part of the
	  username is hashed. This can be used to implement per-domain
	  backends (which allows safely accessing shared mailboxes within
	+ Added a "session ID" string for imap/pop3 connections, available
	  in %{session} variable. The session ID passes through Dovecot
	  IMAP/POP3 proxying to backend server. The same session ID is can be
	  reused after a long time (currently a bit under 9 years). 
	+ passdb checkpassword: Support "credentials lookups" (for
	  non-plaintext auth and for lmtp_proxy lookups)
	+ fts: Added fts_index_timeout setting to abort search if indexing
	  hasn't finished by then (default is to wait forever). 
	- doveadm sync: If mailbox was expunged empty, messages may have
	  become back instead of also being expunged in the other side.
	- director: If user logged into two directors while near user
	  expiration, the directors might have redirected the user to two
	  different backends.
	- imap_id_* settings were ignored before login.
	- Several fixes to mailbox_list_index=yes
	- Previous v2.1.x didn't log all messages at shutdown.
	- mbox: Fixed accessing Dovecot v1.x mbox index files without errors.
