Indeed. Sorry. I never built that interface to pass back that data to
the callout code. Probably because I was thinking mainly of sender
callouts, when you presumbably do want to "be" the same host as is
receiving the message. Even more probably, it just got overlooked.

There is a large WishList item to merge the smtp transport code and the
callout code so that they don't suffer from these kinds of problem.
However, it does not look as if it is likely to be done at all soon.
I will add another WishList item that mentions this particular issue.
