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/
