Spam's a universal problem, of course, and it'll be a while before the
legislators catch up, though things are gradually happening.  This
particular issue is forgery, of course; I don't have much hope, but I
have an AUP which attaches a charge of $25,000 per use of our name.  I
don't see a bat's chance in hell of seeing that money at the moment,
but who knows what happens in the future?  See

Another thing you can try is SPF, the sender policy framework.  It's a
DNS extension that says where mail from you can come from.  See
http://spf.pobox.com/ for more details.  AOL is using it:

aol.com text = "v=spf1 ip4:152.163.225.0/24 ip4:205.188.139.0/24 ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24 ip4:64.12.136.0/23 ip4:64.12.138.0/24 ptr:mx.aol.com ?all"

I suspect that they would not block you if you have SPF DNS records.

That may change.
