SPAM Problem

[Aaron Siegel]

Hello

This message is off topic but I was not sure were else I can go to get help 
with my problem.  For the past week I have been receiving messages from 
various mail servers which have bounced messages I have not sent but have my 
email address as the originator of the bounced message. I believe there are 
some SPAMers using my email address on their SPAM. I would really like to 
avoid changing my domain name.  Has anyone experienced this problem? Is there 
something I can do?  

Thank you 
Aaron
