dovecot - Mar 2014 - Pigeonhole Sieve Extprograms Plugin

Hi,

I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which
should contain the "sieve_extprograms" plugin and thus also the
vnd.dovecot.{pipe,filter,execute} capabilities.

However when I add
require "vnd.dovecot.filter";
to my sieve script via managesieve, the server reports
error: require command: unknown Sieve capability: 'vnd.dovecot.filter'

What am I missing and what should I do to get pipe/filter/execute to
work?

postconf -n attached.

Nils

Hi,

I think you are missing something along these lines:

plugin {
   sieve_plugins = sieve_extprograms
   sieve_global_extensions = +vnd.dovecot.filter
   sieve_extensions = +vnd.dovecot.filter
}

Also, I'm not sure what wheezy-backports package does, but the same 
version of Dovecot for Jessie looks for sieve plugins libraries under 
/usr/lib/dovecot/modules/sieve directory, whereas the dovecot-sieve 
package puts them into /usr/lib/dovecot/modules, causing Dovecot to 
throw errors (as it's unable to find them.)

Made it work by creating a symlink /usr/lib/dovecot/modules/sieve 
pointing to ../modules. I suspect this can cause breakage during 
dovecot-sieve update (if they ever get to put those files to the right 
place), so better watch that.
