Maybe I am missing something, but if a message is getting delivered to
a given account, then either the account name and the name of the local
machine appear somewhere in the headers or they don't.  If they do then
you don't send an "away service" message, otherwise you do.

If you have many accounts which redistribute received mail to a central
one, there still is no problem if the redistribution CORRECTLY includes
the redistributed address.  Notice I said redistribute, not forward.  You,
of course, know the distinction.

Therefore, Erik's solution still holds.  What am I missing?
