Hi guys,
coming from CPanel I wonder if there is a similar way with DA filter or Spamassassin to reply "No such user" when receiving emails that are blacklisted by ip or word or address.
I mean a reject (a 5xx code in the server transaction) not a bounce back (a reply after accepting the email). This would be a very nice way to fight spam. Simply dropping emails, for a spammer means: "Email delivered OK, I'll do it again and forever". Having a 5xx error means: "I'm wasting time with a dead email, I'm better remove it".
