v2.2.2 released

20 May '13

http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz.sig It's been a while since v2.2.1. I think all of the bad bugs in v2.2 series should be fixed by now, so here's a new release. I think there are still some small URLAUTH bugs left though, so you might want to wait before enabling it in production (imap_urlauth_host is empty by default, which disables it). + zlib: Keep the last mail cached uncompressed in a temp file. This fixes performance when doing small partial fetches from a large mail. + acl: If plugin { acl_defaults_from_inbox = yes } is set, get the default ACLs for private and shared namespaces from the user's INBOX. (This probably will become default in v2.3.) + pop3: Added pop3_deleted_flag setting to switch POP3 deletions to only hide the messages from POP3, but still be visible via IMAP. - ACL plugin: Mailbox creation wasn't actually checking any ACLs and always succeeded (due to some v2.2 API changes). The created mailbox couldn't have been accessed though, so this couldn't have caused any data leak. - IMAP: Various URLAUTH fixes. - IMAP: Fixed a hang with invalid APPEND parameters. - IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag. - mailbox_list_index=yes still caused crashes. - maildir: Fixed a crash after dovecot-keywords file was re-read. - maildir: If files had reappeared unexpectedly to a Maildir, they were ignored until index files were deleted. - Maildir: Fixed handling over 26 keywords in a mailbox. - Maildir++: Fixed mail_shared_explicit_inbox=no - namespace { prefix="" list=no } was listing mailboxes. - imap/pop3-login proxying: Fixed a crash if TCP connection succeeded, but the remote login timed out. - Case-insensitive search/sort didn't work correctly for all unicode characters, as specified by i;unicode-casemap comparator. If full text search indexes were used, they need to be rebuilt for old mails to be handled correctly. (This bug has existed always in Dovecot.)

Released Pigeonhole v0.4.0 for Dovecot v2.2.1.
by Stephan Bosch 09 May '13

09 May '13

Hello Dovecot users, I finally release the first version of Pigeonhole v0.4 for Dovecot v2.2. The main reason for the delay was that some unexpected (design) problems occurred with the new doveadm-sieve plugin, which allows synchronizing sieve scripts using doveadm sync. One important change is that I incorporated the extprograms plugin into the main Pigeonhole release. With this plugin it is possible to execute administrator-controlled external programs (shell scripts) from the Sieve interpreter, e.g. for special message delivery, filtering and string manipulation. The list of new features is not that impressive. I've been working on IMAP URLAUTH, IMAP CATENATE and HTTP support for Dovecot. Currently, I'm building an SMTP submission proxy server. After all that I plan to spend more time on Sieve development. One of the most important issues on my list is implementing support for using alternative types of storage (e.g. a database) for Sieve scripts, rather than only a filesystem directory as it is now. Changelog v0.4.0: + Added doveadm-sieve plugin that provides the possibility to sync Sieve scripts using doveadm sync along with the user's mailboxes. + Added the Sieve extprograms plugin to the main Pigeonhole package. It is still a plugin, but it is now included so that a separate compile is no longer necessary and distributors are likely to include it. The extprograms plugin provides Sieve language extensions that allows executing (administrator-controlled) external programs for message delivery, message filtering and string manipulation. Refer to doc/plugins/sieve_extprograms.txt for more information. + Added debug message showing Pigeonhole version at initialization. Makes it very clear that the plugin is properly loaded. + Finished implementation of the Sieve include extension. It should now fully conform to RFC 6609. The main addition is the new :optional tag which makes the include command ignore missing included scripts without an error. + Finished implementation of the Sieve environment extension as much as possible. Environment items "location", "phase" and "domain" now also return a usable value. The release is available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.0.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

Released Pigeonhole v0.3.5 for Dovecot v2.1.16
by Stephan Bosch 09 May '13

09 May '13

Hello Dovecot users, Before I release the first version of Pigeonhole v0.4, I quickly release a few small but important fixes for Pigeonhole v0.3. Changelog v0.3.5: - Sieve editheader extension: fixed interaction with the Sieve body extension. If used together, the deleteheader action could fail after a body test was performed. - Test suite: fixed a time zone dependency in the Sieve date extension tests. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.5.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.5.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.

v2.2.0 released
by Timo Sirainen 12 Apr '13

12 Apr '13

http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.0.tar.gz.sig Everything now seems to be stable and working in v2.2, so I can finally move onto developing great new interesting features for v2.3. :) My company has also launched a web shop where you can buy various products. One of them is cheap access to Dovecot enterprise edition repositories, which are basically same as regular Dovecot releases, except they are kept patched with the latest important bugfixes. We currently have releases for RHEL/CentOS 5 and 6, Debian Squeeze and Ubuntu 12.04 LTS. By buying Dovecot-EE you'll also get a 30 day demo license for object storages, if you want to try it out. http://shop.dovecot.fi/ * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. * LDA/LMTP: If saving a mail brings user from under quota to over quota, allow it based on quota_grace setting (default: 10% above quota limit). * pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock file instead of actually locking the mailbox (and causing IMAP/LDA/LMTP to wait for the POP3 session to close). * mail_shared_explicit_inbox setting's default switched to "no". * ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and pop3c_ssl_ca_dir settings. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

v2.2.rc7 released

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz.sig OK, still not quite v2.2.0, but now it's definitely very close. :) * checkpasword: AUTH_PASSWORD environment is no longer set. * Running dsync no longer triggers quota warnings. + dsync: Commit large transactions every 100 new messages, so if a large sync crashes it doesn't have to be restarted from the beginning. - replicator: doveadm commands and user list export may have skipped some users. - Various fixes to mailbox_list_index=yes

v2.2.rc6 released
by Timo Sirainen 08 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz.sig Some more fixes to bugs I noticed today while trying out some new things in production. Note especially the replicator-doveadm socket change, see http://wiki2.dovecot.org/Replication for how to configure it. This change allowed local replicator to notify the remote replicator about user being synced. * replicator: Don't create replicator-doveadm socket by default. This way doveadm replicator commands don't accidentally start an unconfigured replicator server. + replicator: Have remote dsync notify the remote replicator that a user was just synced. This way the replicators are kept roughly in sync. + Added ssl_client_ca_file to specify the CA certs as a file. This is needed (instead of ssl_client_ca_dir) in RedHat-based systems. + Added "doveadm fs" commands, mainly to debug lib-fs backends. - Mailbox list indexes weren't using proper file permissions based on the root directory.

[Dovecot] Released Pigeonhole v0.3.4 for Dovecot v2.1.16
by Stephan Bosch 06 Apr '13

06 Apr '13

Hello Dovecot users, Much time passed since I last released a new Pigeonhole, so quite a few unreleased fixes were pending until now. Development of new features is shifted to the upcoming Pigeonhole v0.4 for Dovecot v2.2. I intend to release v0.4.0 shortly after Dovecot v2.2.0. Changelog v0.3.4: * Changed error handling to be less of a nuisance for administrators. Strictly user-caused errors are only reported in user log. Some errors are logged as info instead. * Sieve: Changed behavior of redirect in case of a duplicate message delivery or a mail loop. If a duplicate is detected the implicit keep is canceled, as though the redirect was successful. This prevents getting local deliveries. The original SMTP recipient is used when it is available to augment the entry in the LDA duplicate database. This way, duplicates are only detected when (initially) addressed to the same recipient. + Sieve vnd.dovecot.duplicate extension: added new features to the duplicate test, making it possible to manually compose the key value for duplicate checking. This extension is in the process of being standardized: https://tools.ietf.org/html/draft-bosch-sieve-duplicate-01 + Sieve date extension: generate warning when invalid date part is specified. - Sieve editheader extension: fixed crash occurring when addheader :last was used. - Sieve include extension: fixed missing error cleanup that caused a resource leak. - Sieve vacation extension: fixed determination of From: address for when sieve_vacation_dont_check_recipient is active. - Sieve tools: the -D option wasn't enabled and documented for all tools. - Sieve dict script storage: fixed potential segfault occurring when dict initialization fails. - ManageSieve: fixed bug in skipping of CRLF at end of AUTHENTICATE command. - ManageSieve: fixed handling of unknown commands pre-login. - Fixed compile on Mageia Linux. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.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

v2.2.rc4 released
by Timo Sirainen 05 Apr '13

05 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz.sig A lot of small random fixes. Some last minute major cleanups/fixes to lib-http and lib-ssl-iostream error handling, which makes them much easier to debug if something goes wrong (so e.g. if https site has invalid certificate, the caller gets error message saying that, including the part of the cert that couldn't be validated). I don't have anything important left in my v2.2 TODO. It passes all my tests. So I'm hoping for v2.2.0 release any day now. + Added "doveadm replicator" commands - Larger changes to lib-http and lib-ssl-iostream error handling. The API caller can now get the exact error message as a string. - Various bugfixes to LDAP changes in rc3
