I started to get some spam mails to a unique user, and that user does not exist in our system.
so I want that all mail for that nonexistent user gets discard.
is this possible?
[update]
my scenario is like this:
- we have a few defined users.
- we have a unique account to get all mail that get all mail (for undefined accounts), D_PASS and luser_relay.
- spamassassin usually score and discard the mail marked as spam.
- we started to receive some spam and their score like not spam, but is only to one unique (nonexistent) account.
- I want to discard all mail to that user, I don't care about the score.
