A Spammer is Spoofing My Email Address

How fun.  Imagine my delight to wake up the last couple of days to find thousands of bounced emails - all with my address in the From: line.  It's such an honor to see my address associated with other legitimate brands that are so proven in the fields of appendage enlargement. 

Here's what happens...

A spammer needs to send spam emails and they don't want to use an address associated with them.  So, they add someone else's address to the From: field of the email.  When the email bounces, it comes to the person's address. In this case, me.

Spoofing is a pretty common problem, but still painful. Apparently, there is little that can be done aside from filtering the incoming messages and hoping that people don't think you're sending the spam.  I'm looking into adding an SPF (Sender Policy Framework) record, which can also help, I hear. Any other tips?
