There was a real discussion about how to deal with a single SMTP 
server serving multiple host names. It was pretty much decided that 
this was a problem for TLS, not for this protocol. Chris sent the 
above proposal, I pointed out that this was a protocol change, and 
the conversation died.

I would like to resolve this soon so that we can finish this 
document. Do people like Chris' suggestion? Should we just ignore the 
problem?
