I had a user account on my system many years ago (like 12) that continues to get many email attempts. Is it possible to add servers trying to send to this address to a blacklist.
NB: I'm not talking about any no such user error, but this specific user who could not possibly be getting legitimate mail. (and yes, email attempts to this user account have shot up dramatically in the last year). -- I DID NOT SEE ELVIS Bart chalkboard Ep. 7G07
