I have a customer that their local tech guy removed relay restriction on the local mail server.
They are now relaying 100,000+ spam messages. I can't use the queue tracker to clean them. I delete a que with not NDR and seconds later it is over 1000 again.
The mail.que file is 29GB
Is there some trick to cleaning out the pending messages? Can I drop the time out to minutes to get them to clear out faster? I'm also thinking turn off NDR for external.
Any ideas or tips to get this cleaned up (I've already recreated the SMTP connector so that it will not relay).
