They could always shotgun the problem like optonline did and block port 25 to their clients. They could make exceptions for clients with dedicated IPs (if they have them) so that they can run mail servers (tons of mail servers reject mail from dynamic ips anyway).
Right now, the bulk of the SPAM that I see comes from zombies on major ISPs, open proxies/relays and "spam houses". The zombies are fairly easy to block as are the spam houses (the companies that pose as "legitimate" but are really just spammers who buy email addresses). The open proxies are a bit more difficult but most big spammers use zombies nowadays. Regards, Howie --- On Wednesday, February 09, 2005 4:10 PM, Jim Davis scribed: --- > > > True - I've no doubt.
