I have my mail server setup to do masquerading (user@mydomain to user@otherdomain). How ever spammer were using it to send mail. So I setup my firewall to only allow mail to be sent to otherdomain from mydomain. now I have all this in my mail queue and will not go away. Can anyone tell me how to stop this and how to make these go away?
