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".

Ha! Thanks for the confidence in my coding skills.

Does the sieve plugin use libsieve or the sieve binary?

"i like .net for the same reason i like gentoo. it keeps all the
 people with no clue from writing c code, which is much harder for me
 to identify and eliminate from my systems. in the same way that
 gentoo gives those people a place to be that isn't in debian"
