Name        : dovecot
Product     : Fedora 20
Version     : 2.2.15
Release     : 1.fc20
URL         : http://www.dovecot.org/
Summary     : Secure imap and pop3 server
Description :
Dovecot is an IMAP server for Linux/UNIX-like systems, written with security
primarily in mind.  It also contains a small POP3 server.  It supports mail
in either of maildir or mbox formats.

The SQL drivers and authentication plug-ins are in their subpackages.

--------------------------------------------------------------------------------
Update Information:

- Fixed several race conditions with dovecot.index.cache handling that may have caused unnecessary "cache is corrupted" errors.
- auth: If auth client listed userdb and disconnected before finishing, the auth worker process got stuck (and eventually all workers could get used up and requests would start failing).
- lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either.
- "Out of disk space" errors are now treated as temporary errors
(not the same as "Out of disk quota").
- replication plugin: Use replication only for users who have a
non-empty mail_replica setting.
- lmtp proxy: Log a line about each mail delivery.
- Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports).
- Rawlog settings can use tcp:<host>:<port> as the path.
- virtual plugin: Don't keep more than virtual_max_open_mailboxes
(default 64) number of backend mailboxes open.
- SSL/TLS compression can be disabled with ssl_options=no_compression
- acl: Global ACL file now supports "quotes" around patterns.
- Added last-login plugin to set user's last-login timestamp on login.
- LDAP auth: Allow passdb credentials lookup also with auth_bind=yes	
- IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks.
- passdb static treated missing password field the same as an empty password field.
- mdbox: Fixed potential infinite looping when scanning a broken
mdbox file.
- imap-login, pop3-login: Fixed potential crashes when client
disconnected unexpectedly.
- imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks.
- lmtp proxy: The proxy sometimes delivered empty mails in error
situations or potentially delivered truncated mails.
- fts-lucene: If whitespace_chars was set, we may have ended up
indexing some garbage words, growing the index size unnecessarily.
- -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable.
- quota: Quota recalculation didn't include INBOX in some setups.
- Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed.
- doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

* Wed Nov 20 2013 Michal Hlavinka <mhlavink at redhat.com> - 1:2.2.8-1
- Fixed infinite loop in message parsing if message ends with
  "--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't
  trigger this, because messages must end with an "LF.". A user could
  trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
  sent to it.
- replicator: Database wasn't being exported to disk every 15 minutes
  as it should have. Instead it was being imported, causing "doveadm
  replicator remove" commands to not work very well.
