http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc4.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc4.tar.gz.sig I'm pretty hopeful that virtual mailbox code is finally crash-free. If people don't find many problems from this release, I'm thinking that rc5 could come in a couple of weeks and that would be renamed to v1.2.0 after a week or so if no one has reported bugs. v1.2.rc4 2009-05-17 Timo Sirainen <tss(a)iki.fi> * If /dev/arandom exists, use it instead of /dev/urandom (OpenBSD). * When logging to a file, the lines now start with a timestamp instead of "dovecot: " prefix. + IMAP: When multiple commands are pipelined, try harder to combine their mailbox syncing together. For example with Maildir pipelining STORE 1:* +FLAGS \Deleted and EXPUNGE commands the files won't be unnecessarily rename()d before being unlink()ed. + imap-proxy: Send backend's CAPABILITY if it's different from what was sent to client before. + IMAP: struct mail now keeps track of all kinds of statistics, such as number of open()s, stat()s, bytes read, etc. These fields could be exported by some kind of a statistics plugin (not included yet). + IMAP: SEARCH command now dynamically figures out how to run about 0.20 .. 0.25 seconds before seeing if there's other work to do. This makes the SEARCH performance much better. - Fixes to shared mailbox handling. - Fixes to virtual mailboxes. - THREAD command could have crashed. - Fixes to expire-tool. - mbox: Don't break if From_-line is preceded by CRLF (instead of LF). - dict process wasn't restarted after SIGHUP was sent to master.

v1.1.15 released

http://dovecot.org/releases/1.1/dovecot-1.1.15.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.15.tar.gz.sig The command pipelining fix is pretty interesting. Wonder how much it improves performance, especially when deleting lots of messages from a large mailbox. v1.1.15 2009-05-17 Timo Sirainen <tss(a)iki.fi> + IMAP: When multiple commands are pipelined, try harder to combine their mailbox syncing together. For example with Maildir pipelining STORE 1:* +FLAGS \Deleted and EXPUNGE commands the files won't be unnecessarily rename()d before being unlink()ed. - IMAP: SEARCH command was slower than necessary in a large mailbox. - deliver: When forwarding messages, if -f parameter was given, it should have been used as the Return-Path. - Maildir saving: Fixed race condition bugs in uidlist handling, causing files to be given new UIDs sometimes. - mbox: Don't crash when expunging all messages and file doesn't end with [CR]LF. - expire-tool: Use mail_uid and mail_gid settings if userdb doesn't return uid/gid. - Berkeley DB dict: Transaction rollbacking was implemented wrong. - zlib plugin: Some email / FETCH command combinations could have disconnected the client or sent compressed garbage.

Released Sieve v0.1.5 and ManageSieve v0.11.4 for Dovecot v1.2.rc3 and ManageSieve v0.10.6 for Dovecot v1.1.14
by Stephan Bosch 18 Apr '09

18 Apr '09

Hello Dovecot users, This is a simultaneous release of new versions of Sieve-related software for Dovecot v1.1 and v1.2. Only the Sieve implementation itself has seen significant development. The ManageSieve packages only have small fixes and the ManageSieve patches are updated as usual to match the new Dovecot releases. Changelog Sieve v0.1.5: * Ported the implementation of the Sieve include extension to the latest draft. This means that the import and export commands are replaced by a new command called global. The import and export commands are now DEPRICATED and are mere aliases for the global command. The new specification also adds the :once modifier to the include command. The also newly specified global.* variable namespace is not implemented yet as support for variable namespaces is currently missing. * Did a major rework of the multiscript support for better error handling and made sure that persistent global scripts (sieve_before/sieve_after) are always executed, even when the user does not have a script of his own and a global default is missing. + Provided basic support for the environment extension. Currenly, the name, version and host items are useful. Others are pending. + Improved error message that is presented when an unknown Sieve extension is provided as argument to the require command. It now notifies the user that Sieve core commands do not need to be specified in require. - Fixed bug in includes at levels deeper than one. - Fixed bug in address matching that was caused by the failure to handle group specifications. In Dovecot, these are marked by address items with NULL elements, which causes a segfault if not considered. The group 'undisclosed-recipients:;' in particular triggered this bug. Bug reported by Bernhard Schmidt. Changelog ManageSieve v0.11.4 (Dovecot v1.2.rc3): * Adjusted to changes in the Dovecot signal handler API. Changelog ManageSieve v0.10.6 (Dovecot v1.1.14): - Fixed small problems in the login proxy support. -- The releases are available as follows: Sieve for Dovecot 1.2: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz.sig ManageSieve for Dovecot v1.2 (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… ManageSieve + patch for Dovecot v1.1 (package + patch): http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

v1.1.14 and v1.2.rc3 released
by Timo Sirainen 17 Apr '09

17 Apr '09

http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz.sig http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz.sig Fixed lots of bugs in v1.2 related to shared mailboxes and virtual mailboxes. Keep on testing and sending bug reports and hopefully we'll get v1.2.0 release out soon. :) Also v1.3 branch has started and it's coming along nicely. Multi-dbox is working and looks like its performance is very nice. LMTP server is basically implemented, except master process doesn't start it. Adding the master code started becoming so annoying that I think I'll finally finish the master process rewrite, or at least the most important parts of it. So looks like v1.3 might become v2.0 after all. v1.1.14 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP: Don't allow APPEND to specify INTERNALDATE more than 2 hours into future. With Maildir future INTERNALDATEs may mess up incremental backups. - Date: header was always being added to cache file when saving messages, even if clients didn't really want it. This caused POP3-only users to have dovecot.index.cache file unneededly. - Character set conversion in specific mails may have caused Dovecot to allocate all the available memory (in default configuration dying after having allocated 256 MB). This happened only while searching messages. - Message address parser didn't handle empty group:; correctly. - imap/pop3-login: Don't crash when shutting down and destroying clients. - deliver wasn't using mail_access_groups setting. - mbox: When doing autodetection, if mbox didn't find an existing mail directory it just went and created it anyway, instead of failing the storage creation. - Fixed some error handling in maildir and index code. v1.2.rc3 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP proxy no longer simply forwards tagged reply from remote authentication command. It's now done only if the remote server sent a [resp-code], otherwise all failure strings are converted to Dovecot's "Authentication failed." to make sure that if remote isn't using Dovecot it won't reveal user's existence. + Quota roots can now specify which namespace's quota they're tracking. This is probably the most useful for giving public namespaces a quota. + Added imap_idle_notify_interval setting. - Fixes to shared mailbox handling - Fixes to virtual mailboxes - Fixed compiling with some FreeBSD and NetBSD versions - THREAD REFS still might have returned one (0) at the beginning. - deliver wasn't using mail_access_groups setting. - Fixed some error handling in maildir and index code.

v1.2.rc2 released

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc2.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc2.tar.gz.sig Somehow I forgot to check that "make distcheck" finished successfully in rc1, so rc1 didn't actually even fully compile. No other changes since rc1 than the compile fix.

v1.2.rc1 released
by Timo Sirainen 03 Apr '09

03 Apr '09

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz.sig I think it's time to get v1.2.0 out soon. Shared mailbox code is beginning to look like it's working and other features should work fine also. I don't really see any reasons to delay it, so please start testing and let's get the last bugs found and fixed quickly. I'm also going to start v1.3 branch soon with configuration rewrite and multi-dbox support. Changes since beta4: * Renamed THREAD X-REFERENCES2 to THREAD REFS (from INTHREAD draft) + When a process is killed, show the signal code and the sending process's pid and uid. + quota-fs: Added support for NFS group quota. - Several fixes to shared mailboxes and ACLs - Removed umask setting. We're nowadays creating practically all files with proper umasks. - acl: Dropped default ACL cache timeout from 5 minutes to 30 seconds. - fts-solr fixes - virtual mailbox fixes - Write to main index file less often.

v1.2.beta4 released
by Timo Sirainen 25 Mar '09

25 Mar '09

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz.sig This release fixes a memory corruption bug related to MODSEQ handling in earlier v1.2 releases. Memory corruption means that it's a security bug and possibly exploitable. MODSEQ code is new in v1.2, so v1.1 and older releases are not affected. Other than that, there is an ESORT bugfix and other fixes that were added to v1.1 branch too.

Released Sieve v0.1.4
by Stephan Bosch 21 Mar '09

21 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems.

v1.1.12 and v1.2.beta2 released
by Timo Sirainen 14 Mar '09

14 Mar '09

http://dovecot.org/releases/1.1/dovecot-1.1.12.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.12.tar.gz.sig http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta2.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta2.tar.gz.sig I thought I'd do a double-release since it's Friday the 13th. v1.2.0 is getting closer, mainly some ACL fixes left. Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.
