Another thing that the recipient mailserver should check for is the domain sent with the helo/ehlo command, many sendmail installations simply send localhost, which is invalid according to the RFC, and should also be rejected. So what you have to do is basically use your ISP smtp server to send mail. Or setup your own, which means you need a static IP. I have been have been using these measures on my mailservers for the past 3-4 months or so reducing SPAM by over 90% with only one legitimate mailserver being refused. A polite but firm email to the administrator fixed that.
