Fedora Update Notification
FEDORA-2017-da4ed58fd5
2017-04-27 14:02:15.390632
——————————————————————————–

Name        : dovecot
Product     : Fedora 24
Version     : 2.2.29.1
Release     : 1.fc24
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:

  + quota: Add plugin { quota_max_mail_size } setting to limit the    maximum
individual mail size that can be saved.  + imapc: Add imapc_features=delay-
login. If set, connecting to the    remote IMAP server isn’t done until it’s
necessary.  + imapc: Add imapc_connection_retry_count and
imapc_connection_retry_interval settings.  + imap, pop3, indexer-worker: Add
(deinit) to process title before    autoexpunging runs.  + Added %{encrypt} and
%{decrypt} variables  + imap/pop3 proxy: Log proxy state in errors as human-
readable string.  + imap/pop3-login: All forward_* extra fields returned by
passdb are    sent to the next hop when proxying using ID/XCLIENT commands. On
the    receiving side these fields are imported and sent to auth process
where they’re accessible via %{passdb:forward_*}. This is done only    if the
sending IP address matches login_trusted_networks.  + imap-login: If
imap_id_retain=yes, send the IMAP ID string to    auth process. %{client_id}
expands to it in auth process. The ID    string is also sent to the next hop
when proxying.  + passdb imap: Use ssl_client_ca_* settings for CA validation.
– fts-tika: Fixed crash when parsing attachment without    Content-Disposition
header. Broken by 2.2.28.  – trash plugin was broken in 2.2.28  – auth: When
passdb/userdb lookups were done via auth-workers, too much    data was added to
auth cache. This could have resulted in wrong    replies when using multiple
passdbs/userdbs.  – auth: passdb { skip & mechanisms } were ignored for the
first passdb  – oauth2: Various fixes, including fixes to crashes  – dsync:
Large Sieve scripts (or other large metadata) weren’t always    synced.  – Index
rebuild (e.g. doveadm force-resync) set all mails as \Recent  – imap-hibernate:
%{userdb:*} wasn’t expanded in mail_log_prefix  – doveadm: Exit codes weren’t
preserved when proxying commands via    doveadm-server. Almost all errors used
exit code 75 (tempfail).  – ACLs weren’t applied to not-yet-existing autocreated
mailboxes.  – Fixed a potential crash when parsing a broken message header.  –
cassandra: Fallback consistency settings weren’t working correctly.  – doveadm
director status <user>: “Initial config” was always empty  – imapc: Various
reconnection fixes.
