Hi
I'm using a few pipe rules (see http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms). However, these rules are not shown in Roundcube and - since Roundcube fully regenerates the roundcube.sieve file - they are lost whenever other filters are edited in Roundcube.
How about adding support for extprograms to Roundcube?
IMHO, there should be a config setting to enable or disable (default) this feature. And it could be limited to the pipe command for starters.
What do you think?
