Released Pigeonhole v0.4.13 for Dovecot v2.2.22.
by Stephan Bosch 18 Mar '16

18 Mar '16

Hello Dovecot users, Here is the final v0.4.13 release of Pigeonhole for Dovecot v2.2.22. Nothing changed since the RC. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.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

Xi has a new home
by Stephan Bosch 17 Mar '16

17 Mar '16

Hi, The automatic package builder Xi has moved to system within the Dovecot infrastructure. This also means that the repositories are available at a new host name: xi.dovecot.fi. The old host name still works and is a CNAME pointing to the new venue. I expect the old domain to be active for years to come. So, there is no need to update your /etc/apt/sources.list right away. Still, it is a good idea to do so. I've updated the wiki accordingly. Regards, Stephan.

Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.

Hello Dovecot users, Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only with warnings. That is the primary reason for this new release. However, there are also a few significant changes as listed below. When no significant problems are reported, a definitive release will follow closely after Dovecot v2.2.22 is released. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64.

http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz.sig There are some larger changes here, especially to doveadm to make it support HTTP API. There's still time to do smaller tweaks to the API, so let us know if you have some improvement ideas. Note that the API was designed to look mostly like JMAP, which we're planning to implement also for v2.3. The plan is to fork v2.3 development tree soon. + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata.
