It seems pretty clear to me that sending mail directly to a post
office server is not something postmaster really supports, given that
the mail needs to arrive as user@poNN.LOCAL. Let's face it, getting
mail from a random non-athena machine at mit to a post office server
with an envelope to of user@poNN.LOCAL is a non-trivial task. If this
were really supported, I'd have to assume that they would also accept
mail to user@poNN.mit.edu.

So, the reason fo this is so that we properly catch mail addressed to
user@foo.LOCAL where foo.mit.edu is the machine receiving the mail.
While I'm pretty sure I could make the sendmail.cf DWYW, I'm not sure
I can do it without potentially leaving some spoog in the address in
some (extremely rare) cases. Given all of this, I think I have to say
that I'm not really convinced this is a bug.
All that said, jhawk@po12.LOCAL. (note the trailing dot) happens to
accidently DWYW.
