It sounds like you've done everything you could. I had this happen to
me. Basically, it stops after a few days unless they use your address
again. At that point you can get them shut down (for those who are
groaning... i've done it). But real spammers just go on and use the next
random person on the 'net.
I wouldn't spend any money on Postini. You've done all of the right
things. And of course, all of your systems and all the systems you know
are not relaying spam! :)
Good luck.
