as state in my initial mail im using mimdedefang right now. but as it
takes influence during the smtp phase (using libmilter).

1. I can't know what all local user are. (before alias expansion)

2. if I would solve problem one I would need spawn several individual
mails (results of the individual spam decision) beeing sent instead of
just the one which was passed from libmilter


I don't wanna say it's completely impossible but during the smtp stage
is not the logical place to do it. I should be done during local
delivery (lmtp). I hacked it directly into deliver() from cyrus but more
correct would be an lmtp proxy or the sieve extension mentioned by rob.
As I had looked on the web I couldn't find anything any software which
could do that right of the box.
