Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.1. You will need this release for Dovecot v2.3.1, because the previous v0.5.0.1 release will not work. Apart from compatibility changes, it only contains bugfixes. Changelog v0.5.1: - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve script. - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not assert crash or log an error for messages that disappear concurrently while applying Sieve scripts. This event is now logged as a debug message. - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.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

Release 2.3.1
by aki.tuomi＠dovecot.fi 27 Mar '18

27 Mar '18

Hi! We are releasing v2.3.1, which mostly consists of bug fixes for 2.3.0, and few improvements. This is also available via https://repo.dovecot.org if you want packages. libsodium support didn't get into this build, due to build environment issues, but 2.3.2 will contain it. * Submission server support improvements and bug fixes - Lots of bug fixes to submission server * API CHANGE: array_idx_modifiable will no longer allocate space - Particularly affects how you should check MODULE_CONTEXT result, or use REQUIRE_MODULE_CONTEXT. + mail_attachment_detection_options setting controls when $HasAttachment and $HasNoAttachment keywords are set for mails. + imap: Support fetching body snippets using FETCH (SNIPPET) or (SNIPPET (LAZY=FUZZY)) + fs-compress: Automatically detect whether input is compressed or not. Prefix the compression algorithm with "maybe-" to enable the detection, for example: "compress:maybe-gz:6:..." + Added settings to change dovecot.index* files' optimization behavior. See https://wiki2.dovecot.org/IndexFiles#Settings + Auth cache can now utilize auth workers to do password hash verification by setting auth_cache_verify_password_with_worker=yes. + Added charset_alias plugin. See https://wiki2.dovecot.org/Plugins/CharsetAlias + imap_logout_format and pop3_logout_format settings now support all of the generic variables (e.g. %{rip}, %{session}, etc.) -- Aki Tuomi Dovecot oy

Released Pigeonhole v0.4.23 for Dovecot v2.2.35.

Hello Dovecot users, Here is a new Pigeonhole release that goes with the new Dovecot v2.2.35 release. This release is not strictly necessary, as previous versions should be usable as well. This release only contains bug fixes. However, considering the rather nasty editheader bug that emerged in the previous release, upgrade is recommended. Changelog v0.4.23: - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not log an error for messages that disappear concurrently while applying Sieve scripts. This is a further improvement on the imapsieve fix in the previous release (which fixed a panic). This event is now logged as a debug message. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.23.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.23.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.

Released Pigeonhole v0.4.22 for Dovecot v2.2.34.

Hello Dovecot users, Here is a new Pigeonhole release that goes with the new Dovecot v2.2.34 release. This release is not strictly necessary, as previous versions should be usable as well. This release only contains bugfixes. Changelog v0.4.22: - Fixed filesystem path handling problem: sieve plugin could have assert-crashed with specific path lengths with: "Panic: file realpath.c: line 86 (path_normalize): assertion failed: (npath_pos + 1 < npath + asize)". - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. - editheader extension: Extensively reworked the low-level implementation of adding and removing headers. This solves a few integer arithmetic problems reported by Clang runtime checks, but also improves code structure and reliability in general. - imapsieve: Fix assert crash occurring when selected messages are expunged concurrently by the time Sieve filter is to be applied. - imap4flags extension: Fix binary byte-code corruption occurring when the setflag, addflag, or removeflag command's flag-list is a variable. - enotify extension: mailto method: Fixed parsing of mailto URI with only a header part. - enotify extension: mailto method: Make sure "From:" header is set to a usable address and not "(null)". - Fixed writing address headers to outgoing messages. It sometimes erroneously applied another layer of MIME header encoding. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.22.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.22.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.
