I've had exactly the same - over the past few days about 10 bounces for 
spam that has used my address, plus I've had colleagues in other companies 
tell me they've had the same.

There's nothing you can do about it - the mail doesn't originate from your 
mail server, but the From and Return-Path headers are set to your address. 
You could try tracing the originating mail server in the headers and 
report the spam to their abuse dept (if they have one) but in the bounces 
I saw most of the headers had been stripped so I couldn't trace it. I had 
a lot of this 3 or 4 years ago and spent time explaining to the 5 or 6 
people that emailed me and complained that it wasn't me and that they 
could verify it by checking the headers - I'm just waiting for complaints 
again this time around, but I just know it'll be much harder to convince 
them I didn't send it as it's more likely to be "newbies" that complain, 
the "techies" will probably have spotted the from address was a fake.

This is just another of those problems you have to live with - it's 
extremely easy to fake a from address, and unless you can determine the 
actual originating IP you'll have trouble getting any action taken.
