I have an Exchange 2010 server at my DR site. It sends outoging mail to a smarthost, let's call the smarthost zix1.
Outgoing mail is not working. Mail vendor says the smarthost is fine. My firewall vendor does not see any traffic coming from my Exchange server at 10.10.10.205, which is the MAPI network IP address.
I did a pathping to zix1 and it's showing the replication network IP address of 10.10.10.204.
Seems like my Exchange server is trying to send out mail or communicate outside with the replication network - is that possible? ANy ideas how to fix it??
