Great Sam!

I see one other useful application of this new "virtual SMTP host/IP"  
functionality: specifying source IP for particular domains in esmtproutes  
file, e.g. some additional parameter like /SOURCE=<IP>. It could help in  
situations where main IP of the mail server is blocked at some domain. I  
have such a case for hotmail.com and forced to relay mail for this domain  
through another server.
