But how about this: in addition to MX hosts, every domain also has one or more MO (mail originator) hosts. Mail servers then get to check the address of the SMTP server they're talking to against the DNS records for the domain in the sender's address. Then customers who use an email address under their ISP's domain have to use the ISP's relay, while people with their own (sub) domain get to use their own.

Google for "RMX DNS". There's a few other proposals too; see for example http://spf.pobox.com/ Mike. -- RAND USR 16514
