I've added this as part of another thread but don't want to lose track of it so here goes:
I have a distribution group in Exchange eg distgroup@mydomain.com
In that distribution group is 2 contacts external to the domain eg me@gmail.com & me@hotmail.com
Mail leaves Exchange and is filtered via the UTM
Now the strange part:
1. If I use an internal user eg somebody@mydomain.com to send the distribution group, exchange forwards it to the UTM which in turn forwards it to both email addresses ie me@gmail.com & me@hotmail.com. The UTM logs it etc and everything works well as it should.
2. If I use an external email address, specifically me@gmail.com and send to dist@mydomain.com, exchange does it's part and sends it to the UTM and the UTM logs email as being sent out (both to me@gmail.com & me@hotmail.com). The mail reaches me@homail.com but not me@gmail.com (the original sending address to the distribution list)
3. If I do the same as above but use me@hotmail.com as the original senders address to the distribution list, mail arrives at me@gmail.com but doesn't at me@hotmail.com (UTM records it as received at both gmail & hotmail servers)
Any ideas?
