On my account (affordablehost), there is a setting that says "what do you want me to do with mail that is sent to xxx.domain-name.com, if a valid email account does not exist?" The choices are to either reject the mail, or send it to a 'catcher' email id. I had it use the 'catcher' for awhile, but the spam was intolerable -- so I set it to 'reject'. Never had a problem since.
