Hello Dovecot users,
Now that Dovecot v2.1.0 is out there, I release Pigeonhole v0.3.0. The
most significant new features are support for the Sieve editheader
extension and the sieve-filter tool. I haven't received much feedback on
these new features, which can either mean that they are mostly bug-free
or that not many people have tried these, so these are still considered
* Renamed sieve_global_path setting to sieve_default for clarity. Old
name is still recognized for backwards compatibility. Support for
the ancient (pre v1.1) name for this setting "global_script_path" is
* Added means to prohibit use of redirect action. Setting
sieve_max_redirects to 0 now means that redirect is disallowed in
stead of unlimited. Default value remains four.
* Fixed interaction of Sieve include extension with ManageSieve. It is
updated to match new requirements in the draft include
specification. Missing included scripts are no longer an error at
* Updated RFC2822 header field body verification to exclude
non-printing characters (RFC5322). Only Sieve actions that can
create unstructured header values (currently enotify/mailto and
editheader) are affected by this change.
+ Completed sieve-filter tool to a useful state. The sieve-filter tool
provides a means to (re)filter messages in a mailbox through a Sieve
+ Implemented the Sieve editheader extension. It is now possible to
add and remove message headers from within Sieve.
+ ManageSieve: added support for reading quoted and literal strings as
a stream. Fixes support for handing large SASL responses (analogous
to similar changes in Dovecot). It is now also allowed to use a
quoted string for the PUTSCRIPT script argument.
+ Added code to cleanup tmp directory in Sieve storage directory
(sieve_dir) every once in a while.
+ Added support for substituting the entire message during Sieve
processing. This is used for the filter action provided by the new
sieve_extprograms plugin (provided separately for now). The filter
action allows passing the message through an external program.
+ Added support for restricting certain Sieve language extensions to
(admin-controled) global scripts. Restricted extensions can be
configured using the new sieve_global_extensions setting. This is
particularly useful for some of the Dovecot-specific (plugin-based)
Sieve extensions, that can be somewhat hazardous when under direct
control of users (e.g. sieve_extprograms).
The release is available as follows:
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.
