[SpamCop-List] Re: Someone is using my domain name to send spam, how do I stop them?

[Andrew Ward]

One thing I've done is to set my domain to "blackhole" any email that is not
addressed to one of the few legitimate addresses. Usually, these bounce
messages come back to something at mydomain where something is not a valid
address. So I don't see these bounce messages, and I worry about joe-jobs a
lot less :-)
