Thanks for all the responses. For the several weeks this has been happening I've been assuming this worm was a Windows problem and that my address was being spoofed. But then I came across a message that had been returned from a client's domain. Granted this is a huge company with any number of people and several websites--but I was alarmed at the coincidence (at least, I hope it was a coincidence). So I wondered if some malware out there had finally found it's way to OS X in spite of no mention of both it and "Macintosh" on the security sites I check when something like this comes up. I appreciate those familiar with these problems answering so quickly.
It sounds like I have to endure these things until someone(s?), somewhere takes care of it on their own computer(s) and there's nothing I can do about it unless I want to track down the advertised ISPs and contact them to put a stop to it. And there is no way I can determine who's computer it was that snatched my domain for it's own use. In the meantime, I'll check out ClamXav and HenWen to see what they offer in terms of peace of mind.
