I actually think it is highly unlikely that with the way spammers work they would try to tailor spam individually for each ISP to get past what they think are its filters. We are not big enough for that. They just throw out 100 million of them and hope say 10 million of them get through and are not too worried if it is 10.0 million or 10.05 million.

Spammers do try to get past filtering, and use different methods for AOL, Hotmail, etc. Some try to poison auto-learning filters as well.

Oh I agree they do - but at the scale of the ISPs with 10 million+ customers or products that are in wide use. I can't see a spammer adjusting anything just because they read on a website that Ihug with 80,000 customers uses Spam Assassin. DPF
