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.

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.
