Well - yes, if on the same server ....

And ISTR, that one or several of the web-interface end-user
tools for setting up forwarders and such DO check at least 'same
box' addresses for validity, else won't 'apply' them.

But it becomes a non-trivial exercise when forwarding is to go
to someone else's MX.

As I never expect M. Perkel to do anything standard, easy, or
direct, at least not on this list.....
