anything i can do about spoofing?

[Charles Mangin]

is there anything i can do about someone spoofing one of my email 
addresses (or that of one of my clients)? i got a bunch of bounces the 
other day from someone is using my name to send out norton spam (with 
lovely links like 
http-www-swmaxxdel-com-il1oololo-0o0olo0os-0os0l5o5-0o50s0o-o1o.us and 
oll02198283l4672lo39102-42l3917y7u123-lo97687o876o58l-olol27373.us fun!)

i suspect there's nothing i can do but respond to any postmaster or 
abuse folk that contact me and tell them to look at the headers to see 
where the mail really came from, but i wonder if there's anything else 
i can do? it's bad enough when i get somebody emailing me that someone 
at my domain sent them a virus (and i can tell them someone with my 
address in their address book caught a virus), but when it looks for 
all the world like i'm trying to sell people pirated software...

ah, the wonders of the internet, right?
