Do not accept mail for non-existent users. If the user doesn't exist, the server should reject the mail with a "550 User Unknown" and it will never get to your mail queue in the first place. If the message is legitimate, the sender will receive the error message. If the message is spam, the spambot will receive the error message. Either way, the error goes directly back to the sender through the same connection used to send the mail. -- Bowie
