Qmail queue has mail stuck for domain we no longer host.

[Tormente]

Looking at the mail queue I notice there is a lot of mail for a domain we no longer host, I empty the queue and it just keeps coming back.

What do I need to do to reject this mail and stop it from clogging up the mail queue?

Seeing the mail queue with tons of spam for that one address/domain, I finally re-added it with NO mail accounts, and set it to reject mail to non-excisint users...

Which is fine as a temporary patch - until we start running of of licenses... any way of doing it without using up a domain license?
