I am getting alot of spam to one of my valid domains but user name is not valid. For example: someuser@mydomain.com. Where "mydomain.com" is valid but not "someuser". What this is doing is bouncing to sender but the sender's email is invalid. The bounce email being sent is stuck on the qmail queue and doesn't seem to disappear. As a result, the queue grows rapidly and eventually no can send email.
Is there a way to automatically delete expired messages in the queue?
