i have been spam by this user "[email protected]" to one of my client domain. it about an email per minute.
he send [email protected] and i have set to dop all the mail that doesn't exit. but before that i have set to reply to user when user doesn't exit.
now l have almost 1000 email from subra that need to sent back to him saying the user doesn't exim but his mailbox is exceeding limit.
what is the best pratice to remove this 1000 email because it choke up my server and wasting my cpu and bandwidth resources.
