Just because you don't have viruses doesn't mean that a misconfiguration 
of your MTA* will cause you to be an open relay and allow others to use 
you to send spam.

* or perhaps you run a web server or other open service on the same box 
that could be hijacked?  Maybe some Windows systems on your network that 
could have a virus?
