Forwarding undeliverables between 3 servers (Netmail, GroupWise, & Exchange)
Posted on 2006-06-23
OK, here's the layout. I know it's asinine, but we're transitioning here
We have a Netmail box, a GroupWise box, and an Exchange box and only one
domain name. The goal is to get internal mail from any 1 server to both
remaining servers. The way I have things now, Netmail is set to forward
local undeliverables to GroupWise, GroupWise is set to forward
undeliverables to Exchange, and Exchange forwards undeliverables back to
Netmail in essentially a 3 server ring.
Here's what happens:
Netmail can send mail to GroupWise, but not Exchange.
GroupWise can send to both.
Exchange can send to both.
Why can't netmail send to exchange via GroupWise?
Does Netmail reformat forwarded messages such that GroupWise might have
forwarding them again? Logically, the problem seems to be with GroupWise.
While it can forward
messages originating from within, it doesn't seem to be forwarding messages
that have already been forwarded once and I'm stumped as to why. Looking
the GWIA log, I can see the connection occur between Netmail and GroupWise,
but nothing after that. The exchange logs show no connection from
GroupWise. Also, GroupWise doesn't return any of these messages to sender.
They seem to simply vanish. Though it shouldn't have anything to do with
this problem, each server will allow relaying from the other two.

Any ideas or nudges in the right direction would be greatly appreciated!
