That is the obvious fix, though I actually have dozens of domains, not all
of which are under my control so I rely on the MTA being able to pretend
it has more than one name.
People often have vanity mail.theirdomain.com type addresses pointed at
ISP mailservers. I would find it hard to believe it is not possible for
Exim to cope with this :(
