I wouldn't recommend this - it may work for some situations, but it
definitely will not work in others - I've known ISPs where they had one
server for incoming mail & virtual hosting and another for outgoing
smtp, and the incoming mailhub (best MX for isp.net) was configured to
not allow itself to be used as a smarthost by the dialin users.

A lot of administrative things become easier that way - if I had any
kind of heavy traffic here I'd have in and out servers.
