v2.1.3 released
by Timo Sirainen 16 Mar '12

16 Mar '12

http://dovecot.org/releases/2.1/dovecot-2.1.3.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.3.tar.gz.sig Do not use v2.1.2 with multi-dbox format, it's broken. I didn't notice that a small optimization I did a few days ago broke mdbox in some situations (when mdbox first created a new m.X file, and later in same session saved another message to it). It's quite a high priority for me to run some automated testing before releasing new versions, for example a small imaptest run with mdbox would have caught this. Perhaps the next release will already have the automated testing.

http://dovecot.org/releases/2.0/dovecot-2.0.19.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.19.tar.gz.sig Hopefully one of the last v2.0.x releases. - IMAP: ENABLE CONDSTORE/QRESYNC + STATUS for a mailbox might not have seen latest external changes to it, like new mails. - imap_id_* settings were ignored before login. - doveadm altmove did too much work sometimes, retrying moves it had already done. - mbox: Fixed accessing Dovecot v1.x mbox index files without errors.

v2.1.2 released
by Timo Sirainen 15 Mar '12

15 Mar '12

http://dovecot.org/releases/2.1/dovecot-2.1.2.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.2.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 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 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.

v2.1.1 released
by Timo Sirainen 23 Feb '12

23 Feb '12

http://dovecot.org/releases/2.1/dovecot-2.1.1.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.1.tar.gz.sig v2.1.0 had a couple of bugs, but overall people have been pretty quiet about it. I'm hoping v2.1.2 won't need to be released for many more weeks. :) BTW. v2.2 branch has also been opened in hg. Not much stuff in there yet though. + dsync: If message with same GUID is saved multiple times in session, copy it instead of re-saving. - acl plugin + autocreated mailboxes crashed when listing mailboxes - doveadm force-resync: Don't skip autocreated mailboxes (especially INBOX). - If process runs out of fds, stop listening for new connections only temporarily, not permanently (avoids hangs with process_limit=1 services) - auth: passdb imap crashed for non-login authentication (e.g. smtp).

Released Pigeonhole v0.3.0 for Dovecot v2.1.0
by Stephan Bosch 16 Feb '12

16 Feb '12

Hello Dovecot users, Now that Dovecot v2.1.0 is out there, I release Pigeonhole v0.3.0. The most significant new features are support for the Sieve editheader extension and the sieve-filter tool. I haven't received much feedback on these new features, which can either mean that they are mostly bug-free or that not many people have tried these, so these are still considered experimental. Changelog v0.3.0: * Renamed sieve_global_path setting to sieve_default for clarity. Old name is still recognized for backwards compatibility. Support for the ancient (pre v1.1) name for this setting "global_script_path" is now dropped. * Added means to prohibit use of redirect action. Setting sieve_max_redirects to 0 now means that redirect is disallowed in stead of unlimited. Default value remains four. * Fixed interaction of Sieve include extension with ManageSieve. It is updated to match new requirements in the draft include specification. Missing included scripts are no longer an error at upload time. * Updated RFC2822 header field body verification to exclude non-printing characters (RFC5322). Only Sieve actions that can create unstructured header values (currently enotify/mailto and editheader) are affected by this change. + Completed sieve-filter tool to a useful state. The sieve-filter tool provides a means to (re)filter messages in a mailbox through a Sieve script. + Implemented the Sieve editheader extension. It is now possible to add and remove message headers from within Sieve. + ManageSieve: added support for reading quoted and literal strings as a stream. Fixes support for handing large SASL responses (analogous to similar changes in Dovecot). It is now also allowed to use a quoted string for the PUTSCRIPT script argument. + Added code to cleanup tmp directory in Sieve storage directory (sieve_dir) every once in a while. + Added support for substituting the entire message during Sieve processing. This is used for the filter action provided by the new sieve_extprograms plugin (provided separately for now). The filter action allows passing the message through an external program. + Added support for restricting certain Sieve language extensions to (admin-controled) global scripts. Restricted extensions can be configured using the new sieve_global_extensions setting. This is particularly useful for some of the Dovecot-specific (plugin-based) Sieve extensions, that can be somewhat hazardous when under direct control of users (e.g. sieve_extprograms). The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.1-pigeonhole-0.3.0.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.1-pigeonhole-0.3.0.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.1.0 released
by Timo Sirainen 16 Feb '12

16 Feb '12

http://dovecot.org/releases/2.1/dovecot-2.1.0.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.0.tar.gz.sig Here's finally the the stable v2.1 release. I expect this release to be quite stable, since it's already being used in several large installations. Changes since rc7: FS layout related crashfix, two man pages added. The biggest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. * Expire plugin: Only go through users listed by userdb iteration. Delete dict rows for nonexistent users, unless expire_keep_nonexistent_users=yes. * Temporary authentication failures sent to IMAP/POP3 clients now includes the server's hostname and timestamp. This makes it easier to find the error message from logs. * dsync was merged into doveadm. There is still "dsync" symlink pointing to "doveadm", which you can use the old way for now. The preferred ways to run dsync are "doveadm sync" (for old "dsync mirror") and "doveadm backup". + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + IMAP SPECIAL-USE extension to describe mailboxes + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. + SCRAM-SHA-1 authentication mechanism by Florian Zeitz + LDAP: Allow building passdb/userdb extra fields from multiple LDAP attributes by using %{ldap:attributeName} variables in the template. + Improved multi-instance support: Track automatically which instances are started up and manage the list with doveadm instance commands. All Dovecot commands now support -i <instance_name> parameter to select the instance (instead of having to use -c <config path>). See instance_name setting. + auth: Implemented support for Postfix's "TCP map" sockets for user existence lookups. - listescape plugin works perfectly now

v2.1.rc7 released
by Timo Sirainen 15 Feb '12

15 Feb '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc7.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc7.tar.gz.sig Okay, one more RC, because I needed a new feature implemented and forgot I wasn't supposed to do any changes anymore before v2.1.0. After that I figured I'll just do a few more changes and release RC7. So, v2.1.0 will probably be released within 1-2 days. So, the one new feature is: + Added ignore_on_failure setting for namespaces. If namespace initialization fails with this enabled (e.g. permission denied), the namespace is silently skipped for the user. Also (not really worth mentioning in NEWS) if you now connect to imap/pop3 port when auth process is misconfigured and dies, instead of hanging the client for 5 mins it gets disconnected pretty much immediately.

Released Pigeonhole v0.2.6 for Dovecot v2.0.18
by Stephan Bosch 13 Feb '12

13 Feb '12

Hello Dovecot users, Pigeonhole v0.2.5 does not compile against the new Dovecot v2.0.18 release. That is why a release a new version now. Other changes are included as well, of which the one regarding the include extension requires special attention; Changelog v0.2.6: * This release fixes unintentional behavior of the include extension. Included script names with a name like "name.sieve" would implicitly map to a script file called "name.sieve" and not "name.sieve.sieve". Keep in mind that the .sieve file extension has no meaning from within the Sieve language. A Sieve script is always stored with an appended .sieve file extension, also when the name already ends with a .sieve suffix. IMPORTANT: Some installations have relied on this unintentional feature, so check your script includes for issues before upgrading. * Matched changes regarding auth_verbose setting in Dovecot. This means that this release will only compile against Dovecot v2.0.18. - Fixed problem in ManageSieve that caused it to omit a WARNINGS response code when the uploaded script compiled with warnings. - Made sure that locations of Sieve error never report `line 0'. - Fixed potential segfault occurring when interpreter initialization fails. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.6.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.6.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
