>Today I started getting slammed with email being returned to me for being undeliverable. No kidding, I've received at least 200 of these since noon. It almost looks like my email address is being used to spam invalid email addresses, and thus it's being returned to me by various email servers.

It could be either just faked sender using your email and/or a spam attack which may contain malware attachments. It has been reported widely and it is quite a problem because it is not easy to fix.

You could try getting your mail server / ISP to filter on source IP or any other identifying characteristics you can identify common to the spam.
