We use sqwebmail primarily to allow users to configure server-side filters, so they don't have to learn another filtering language and we can limit access to the spool directory.

While the maildrop filtering language (pcre) is pretty flexible, the sqwebmail filter interface is quite limited, particularly lacking in the ability to perform actions on more than one condition. Certainly one can't begin to capture all the possibilities within a fixed webform, but as we're moving users from Cyrus/(web)sieve over to Courier/Maildrop, there's numerous instances where an easy cut-over isn't possible within the sqwebmail confines as it lacks the "&&" operator.

Is there any interest in this feature (basically bring the capabilities of sqwebmail/filters upto that of websieve) ?

I'm prepared to spend some time on it (maintain backward compatibility of course); make "Condition:" a set of checkboxes instead of radio buttons; maybe add a couple more arbitrary "Header:" fields with an "any of/all of" option. Or is this already on the todo list somewhere (didn't see it in TODO) ?
