I am trying to deploy dovecot LDA and liking it so far. However, I need to pass the message through some filters before it's delivered to the user (e.g. spamc). I realise I can just set up a chain (postfix delivers to spamc, pipes to foo, pipes to bar, pipes to deliver), but there's no reliable error handling with that approach.
I do this using postfix, dspam via LMTP and deliver, and it does indeed have reliable error handling.
Yeah, but this is not per-user, right? dspam does not need per-user because of it's cookie support, but I have some filters here that aren't this "smart".
Correct, dspam is a little smarter than your average filter, if you're attached to your current filters, perhaps look into amavis and see if it will do the job for you?
What would be really sweet is an LDA plugin that can call arbitrary filters for each message it processes. Has something (obvious) like this been done?
I don't believe this has been coded, but the new deliver uses sieve as a plugin, so I don't see why this shouldn't be possible. You could always write one ;)
Ha! Thanks for the confidence in my coding skills.
Does the sieve plugin use libsieve or the sieve binary?
It's a version of libsieve, but there's no reason a plugin couldn't call an external tool, like the original dspam plugin for imap if you're looking for an example.
