Sendmail Virtual Domains address rewriting [SOLVED...sorta]

[Chris Harms]

After some tinkering, removing the IP address from /etc/hosts was the 
magic bullet.  However, this raises a larger question:
If S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP tells sendmail not to rewrite 
the address (allegedly), why was it still doing it?

Probably a better question for another list, however I imagine more 
people will encounter this with cyrus than with other configurations.  
If someone knows how to correct that issue, please advise.
