I'm using postfix as MTA with dovecot IMAP and trying to get server-side mail filtering with sieve. Everything seems like it's working but it's not. I telnet localhost sive and list rules and it seems like they are active. But it doesn't work. I host two virtual domains with virtual users.
I think that maybe it's something with the transport from postfix => dovecot but i really don't have a clue.
Anyone with a similar setup who can be of any assistance?
