Version     : 2.2.21
Release     : 1.fc23
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:

- dovecot updated to 2.2.21 - doveadm mailbox list (and some others) were broken
in v2.2.20 - director: Fixed making backend changes when running with only a
single director server. - virtual plugin: Fixed crash when trying to open
nonexistent autocreated backend mailbox. - pigeonhole updated to 0.4.10 -
implemented the Sieve mime and foreverypart extensions (RFC 5703). - sieve body
extension: Properly implemented the `:text' body transform. It now extracts text
for HTML message parts. - variables extension: Fixed handling of empty string by
the `:length' set modifier. An empty string yielded an empty string rather than
"0". - Fixed memory leak in the Sieve script byte code dumping facility.
Extension contexts were never actually freed. - doveadm sieve plugin: Fixed
crashes caused by incorrect context allocation in the sieve command
implementations.   ----   + Added mailbox { autoexpunge=<time> } setting. See
http://wiki2.dovecot.org/MailboxSettings for details.  + ssl_options: Added
support for no_ticket  + imap/pop3/managesieve-login: Added
postlogin_socket=path passdb extra    field. This allows replacing the default
service    imap/pop3/managesieve {} settings for specific users (e.g. running
their imap process via valgrind or strace).  + doveadm fetch: Added
date.sent/received/saved.unixtime  + fs-posix: Added mode=auto parameter to set
the created files' and    directories' mode based on the parent dir if it has
setgid-bit.  + director: Support backends having hostnames, which makes it
possible    to verify their SSL certificates.  - director: Directors' state
became desynchronized if doveadm director    commands were used to modify the
same backend in multiple directors    at the same time with conflicting changes.
This fix includes some    extra checks, which makes sure that if such a conflict
still happens    it's automatically fixed. In some situations such an automatic
fix    may now be unnecessarily triggered and an error logged.  - director:
Backend tags weren't working correctly.  - ldap: tls_* settings weren't used for
ldaps URIs.  - ldap, mysql: Fixed setting connect timeout.  - auth: userdb
lookups via auth-worker couldn't change username  - dsync: Fixed handling
deleted directories. Make sure we don't go to    infinite mailbox renaming loop.
- imap: Fixed crash in NOTIFY when there were watched namespaces that    didn't
support NOTIFY.  - imap: After SETMETADATA was used, various commands
(especially FETCH)    could have started hanging when their output was large.  -
stats: Idle sessions weren't refreshed often enough, causing stats    process to
forget them and log errors about unknown sessions when    they were updated
later.  - stats: Fixed "Duplicate session ID" errors when LMTP delivered to
multiple recipients and fts_autoindex=yes.  - zlib plugin: Fixed copying causing
cache corruption when zlib_save    wasn't set, but the source message was
compressed.  - fts-solr: Fixed escaping Solr query parameters.  - lmtp:
quota_full_tempfail=yes was ignored with    lmtp_rcpt_check_quota=yes
