Hello,

I've finished up work on a new plugin for Pigeonhole Sieve: sieve_pipe. It adds a new Sieve extension (vnd.dovecot.pipe) providing a new action command that provides the possibility to pipe messages to external programs (e.g. shell scripts). The programs available to this command are explicitly limited and subject to administrator configuration.

The plugin can currently only be downloaded from the Mercurial repository:

http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe

Check the README/INSTALL files in the repository or the new wiki page for more information:

The specification of the vnd.dovecot.pipe extension can be found here:

I'd still call this thing very much experimental, so be sure to test it extensively first. Don't hesitate to notify me when there are any problems.

Regards,

Stephan.
