What compounds this is that my users in exchange are also local (NIS) to
the internal exim box.
What I'd like to do, is all mail go from external exim (exim1), to
internal exim (exim2), exim2 then looks at exchange to see if they have
an exchange account and if that's true send to the exchange server, and
if not, continue delivering through exim2's routers (forward, majordomo,
etc)
How is this possible?
If it's not I could live with the external exim box sending all email to
the exchange box, and if it's not valid to send to the internal exim
box, but I like the way the previous methodology works as it involves
changes to one box, not 2 or 3
