Or people implement a protocol that doesn't break existing uses of the 
system (let's not forget the issues with many mailing-lists and .forward 
files).

Personally, I like the idea of verifying that an IP address that is 
sending mail is allowed to send mail according to domain X, which is 
either verified by the mail from rhs or by the (he|eh)lo parameter. One 
or the other should be able to be verified; mail from rhs when at the 
home network and (he|eh)lo parameter at remote sites. Checking the MX 
records for each would make a good portion of the current mail servers 
compliant (except those with seperate outbound/inbound servers) and 
having a different tag (txt, new DNS record, special dns tag like 
outmail.fqdn) would allow outbound only servers to quickly meet compliance.

It's quicker and more simplistic than any proposal I've read. It doesn't 
break anonymous forwarding or sending mail through other provider's smtp 
servers. What it does do is verify that someone is responsible for that 
mail connection and that someone is domain X without arguement.

I don't care if envelopes appear to be forged. It's done regularly in 
production. What I do care about is being able to say that someone is 
responsible for the email. If domain X said that a server can send mail 
outbound and it's not the mail I wanted, holder of domain X is liable 
and lawyers can do the dirty work they are paid for. Or at a minimum, I 
can block domain X and not feel bad about it.
