There should be no difficulty at all in doing this.  If they dial into
your network then they use your outgoing mail relay server, and yours
alone.  Period.  (Unless you have some kind of agreement in a roaming
system where you authenticate your own users to someone else's dial-up
and vice versa, in which case you only allow the user to connect to the
the "home" ISP's mail relay host(s).)
