Could you show me the SPF records I would use to indicate that 
mta.example,com is valid as an EHLO but not as a bounce address domain 
while example.com is a valid bounce address domain but not an EHLO.  If 
it'll help, assume they both have an A record of 12.34.56.78.

In real life, lots of people use SPF records for PRA, and there was a loud 
debate before coming to a consensus that the alternative of throwing 
everything away and starting over was unworkable.  I sure wish the SPF 
crowd had a better institutional memory.
