[Dovecot-news] v2.1.2 released


dovecot.org/releases/2.1/dovecot … tar.gz.sig

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 proxy/director.

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 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 domain).
+ 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.
