Im running the following :
Internet feed -> qmail -> Exchange (delivered)
and back out again
Exchange (mail sent from user) -> qmail -> Internet delivery
what I did was, slowly migrate everyone to exchange client (outlook) and
created 2 email address in their profile on exchange ; like [EMAIL PROTECTED]
& [EMAIL PROTECTED]
greg is correct.
in the routing tab in the IMS, I route all "domain.com" back to my qmail
machine (Route to:), this works well becuase any accouts that arent yet on
Exchange will get forwarded back to qmail for delivery, any accounts that
are on exchange will be treated locally and delivered instantly.
I just setup a .qmail for each user to forward messages to exchange using
the [EMAIL PROTECTED] address, once im complete ill add a smtproute
to control/smtproutes
hope this helps,
Stephen

I'd have to doublecheck my systems, but I think that's the default
behavior of Exchange when told to relay. If it doesn't recognize an SMTP
address, it'll punt it whether it is technically "local" or not. If I'm
wrong on this, I'll correct myself tomorrow when I'm back in the office.

Yes. I'm not sure it would go through as many loops as you'd expect,
but I'd have to doublecheck that too. But I'm not sure I see why that
matters - a bad address is a bounce is a bounce, whether it loops or not.
And since your Exchange servers will be using the Exchange directory for
most local mail users, you'll probably see this very rarely.
In short, I wouldn't lose sleep over this aspect of it.

With the caveats of the things I want to doublecheck above, you should
be able to do this with a standard configuration. My config suffers a
little from being legacy (we went from an interim qmail+cyrus system to a
qmail -> exchange system).
I'll take a look tomorrow and comment again.
