Released Pigeonhole v0.5.0 for Dovecot v2.3.0.
by Stephan Bosch 24 Dec '17

24 Dec '17

Hello Dovecot users, Here's the definitive 0.5.0 release. There is one RC fix regarding the duplicate presence of the session ID in the LMTP/LDA log lines produced by the Sieve interpreter. Since this change is relative to the RC, it is not in the change log below. Changelog v0.5.0: * editheader extension: The implementation of header modifications is heavily updated. Although the functionality has not changed, the underlying code was updated to address several static analysis warnings, runtime integer arithmetic warnings (Clang), and to match updates in the Dovecot stream API. + variables extension: Made the maximum scope and variable size configurable. + subaddress: Support multiple recipient_delimiters. - enotify extension: mailto method: Fixed parsing of mailto URI with only a header part. - enotify plugin: mailto method: Make sure the "From:" header is set to a usable address and not "(null)". - Fixed writing address headers to outgoing messages. Sometimes headers were MIME-encoded twice, yielding invalid results. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.0.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.0.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.3.0 released
by Timo Sirainen 22 Dec '17

22 Dec '17

https://dovecot.org/releases/2.3/dovecot-2.3.0.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.0.tar.gz.sig Some random notes: - This release is signed with a new PGP key 0x18A348AEED409DA1 (which is signed by the old key). - This fixes several compiling issues reported for the 2.3 release candidate. Also a few other fixes mainly for submission server and doveadm server. - We're still planning to make at least one (or two) more v2.2.x release before retiring it. It's now time for Christmas holidays though, so the next release will have to wait until the end of January. - We'll start distributing v2.3.x releases in apt/yum repositories in near future. There will be a separate email about it. Some repetition from the release candidate's announcement: There are several new and exciting features in v2.3.0. I'm especially happy about the new logging and statistics code, which will allow us to generate statistics for just about everything. We didn't have time to implement everything we wanted for them yet, and there especially aren't all that many logging events yet that can be used for statistics. We'll implement those to v2.3.1, which might also mean that some of the APIs might still change in v2.3.1 if that's required. We also have new lib-smtp server code, which was used to implement SMTP submission server and do a partial rewrite for LMTP server. Some of the larger changes: * Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3 * Logging rewrite started: Logging is now based on hierarchical events. This makes it possible to do various things, like: 1) giving consistent log prefixes, 2) enabling debug logging with finer granularity, 3) provide logs in more machine readable formats (e.g. json). Everything isn't finished yet, especially a lot of the old logging code still needs to be translated to the new way. * Statistics rewrite started: Stats are now based on (log) events. It's possible to gather statistics about any event that is logged. See http://wiki2.dovecot.org/Statistics for details * ssl_dh setting replaces the old generated ssl-parameters.dat * IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error instead of [UNKNOWNCTE] * Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by default due to potential security reasons (found by cPanel Security Team). + Added support for SMTP submission proxy server, which includes support for BURL and CHUNKING extension. + LMTP rewrite. Supports now CHUNKING extension and mixing of local/proxy recipients. + auth: Support libsodium to add support for ARGON2I and ARGON2ID password schemes. + auth: Support BLF-CRYPT password scheme in all platforms + auth: Added LUA scripting support for passdb/userdb. See https://wiki2.dovecot.org/AuthDatabase/Lua - Input streams are more reliable now when there are errors or when the maximum buffer size is reached. Previously in some situations this could have caused Dovecot to try to read already freed memory. - Output streams weren't previously handling failures when writing a trailer at the end of the stream. This mainly affected encrypt and zlib compress ostreams, which could have silently written truncated files if the last write happened to fail (which shouldn't normally have ever happened). - virtual plugin: Fixed panic when fetching mails from virtual mailboxes with IMAP BINARY extension. - doveadm-server: Fix potential hangs with SSL connections - doveadm proxy: Reading commands' output from v2.2.33+ servers could have caused the output to be corrupted or caused a crash. - Many other smaller fixes

Hello Dovecot users, Here is the Pigeonhole release candidate that goes with the Dovecot v2.3 release candidate. Of course, a large part of this release consists of compatibility changes for Dovecot v2.3. Apart from that, not much changed, just a few additions and fixes that accumulated over the last few months. Most of these changes will be back-ported to Pigeonhole v0.4, but that release will happen a little later. Changelog v0.5.0: * editheader extension: The implementation of header modifications is heavily updated. Although the functionality has not changed, the underlying code was updated to address several static analysis warnings, runtime integer arithmetic warnings (Clang), and to match updates in the Dovecot stream API. + variables extension: Made the maximum scope and variable size configurable. + subaddress: Support multiple recipient_delimiters. - enotify extension: mailto method: Fixed parsing of mailto URI with only a header part. - enotify plugin: mailto method: Make sure the "From:" header is set to a usable address and not "(null)". - Fixed writing address headers to outgoing messages.

https://dovecot.org/releases/2.3/rc/dovecot-2.3.0.rc1.tar.gz https://dovecot.org/releases/2.3/rc/dovecot-2.3.0.rc1.tar.gz.sig It's finally time for v2.3 release branch! There are several new and exciting features in it. I'm especially happy about the new logging and statistics code, which will allow us to generate statistics for just about everything. We didn't have time to implement everything we wanted for them yet, and there especially aren't all that many logging events yet that can be used for statistics.

We also have new lib-smtp server code, which was used to implement SMTP submission server and do a partial rewrite for LMTP server. Please test these before v2.3.0 to make sure we don't have any bad bugs left! BTW. The v2.3.0 will most likely be signed with a new PGP key ED409DA1. Some of the larger changes: * Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3 * Logging rewrite started: Logging is now based on hierarchical events.

Released Pigeonhole v0.4.21 for Dovecot v2.2.33.1.
by Stephan Bosch 13 Oct '17

13 Oct '17

Hello Dovecot users, Here's the definitive 0.4.21 release. There were no changes since the release candidate. Changelog v0.4.21: * redirect action: Always set the X-Sieve-Redirected-From header to sieve_user_email if configured. Before, it would use the envelope recipient instead if available, which makes no sense if the primary e-mail address is available. + vacation extension: Allow ignoring the envelope sender while composing the "To:" header for the reply. Normally, the "To:" header is composed from the address found in the "Sender", "Resent-From" or "From" headers that is equal to the envelope sender. If none is then found, the bare envelope sender is used. This change adds a new setting "sieve_vacation_to_header_ignore_envelope". With this setting enabled, the "To:" header is always composed from those headers in the source message. The new setting thus allows ignoring the envelope, which is useful e.g. when SRS is used. + vacation extension: Compose the "To:" header from the full sender address found in the first "Sender:", "From:" or "Resent-From:" header. Before, it would create a "To:" header without a phrase part. The new behavior is nicer, since the reply will be addressed to the sender by name if possible. - LDA Sieve plugin: Fixed sequential execution of LDAP-based scripts. A missing LDAP-based script could cause the script sequence to exit earlier. - sieve-filter: Removed the (now) duplicate utf8 to mutf7 mailbox name conversion. This caused problems with mailbox names containing UTF-8 characters. The Dovecot API was changed years ago, but apparently sieve-filter was never updated. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.21.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.21.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.

v2.2.33 released
by Timo Sirainen 10 Oct '17

10 Oct '17

https://dovecot.org/releases/2.2/dovecot-2.2.33.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.33.tar.gz.sig We're getting close to the last v2.2.x releases. Hopefully we'll have the first v2.3 beta releases out soon. * doveadm director commands wait for the changes to be visible in the whole ring before they return. This is especially useful in testing. * Environments listed in import_environment setting are now set or preserved when executing standalone commands (e.g. doveadm) + doveadm proxy: Support proxying logs. Previously the logs were visible only in the backend's logs. + Added %{if}, see https://wiki2.dovecot.org/Variables#Conditionals + Added a new notify_status plugin, which can be used to update dict with current status of a mailbox when it changes. See https://wiki2.dovecot.org/Plugins/NotifyStatus + Mailbox list index can be disabled for a namespace by appending ":LISTINDEX=" to location setting. + dsync/imapc: Added dsync_hashed_headers setting to specify which headers are used to match emails. + pop3-migration: Add pop3_migration_ignore_extra_uidls=yes to ignore mails that are visible in POP3 but not IMAP. This could happen if new mails were delivered during the migration run. + pop3-migration: Further improvements to help with Zimbra + pop3-migration: Cache POP3 UIDLs in imapc's dovecot.index.cache if indexes are enabled. These are used to optimize incremental syncs. + cassandra, dict-sql: Use prepared statements if protocol version>3. + auth: Added %{ldap_dn} variable for passdb/userdb ldap - acl: The "create" (k) permission in global acl-file was sometimes ignored, allowing users to create mailboxes when they shouldn't have. - sdbox: Mails were always opened when expunging, unless mail_attachment_fs was explicitly set to empty. - lmtp/doveadm proxy: hostip passdb field was ignored, which caused unnecessary DNS lookups if host field wasn't an IP - lmtp proxy: Fix crash when receiving unexpected reply in RCPT TO - quota_clone: Update also when quota is unlimited (broken in v2.2.31) - mbox, zlib: Fix assert-crash when accessing compressed mbox - doveadm director kick -f parameter didn't work - doveadm director flush <host> resulted flushing all hosts, if <host> wasn't an IP address. - director: Various fixes to handling backend/director changes at abnormal times, especially while ring was unsynced. These could have resulted in crashes, non-optimal behavior or ignoring some of the changes. - director: Use less CPU in imap-login processes when moving/kicking many users. - lmtp: Session IDs were duplicated/confusing with multiple RCPT TOs when lmtp_rcpt_check_quota=yes - doveadm sync -1 fails when local mailboxes exist that do not exist remotely. This commonly happened when lazy_expunge mailbox was autocreated when incremental sync expunged mails. - pop3: rawlog_dir setting didn't work
