So long as all of your users authenticate when submitting emails and
they submit only via your server, you can blacklist your domain in the
spamdyke blacklist_senders file:
@shubes.net
This is counter intuitive, but it works great. Since all legit senders
authenticate, the spamdyke filters don't apply to them. This effectively
says "if the message says it's coming from my domain and the sender
hasn't authenticated, reject it".
