But smtp is listening on second network From: Hank . [mailto:hgedr...@gmail.com] Sent: Thursday, July 07, 2011 10:17 PM To: MS-Exchange Admin Issues Subject: Re: what determines the IP address used in the mail header?
I thought it could be but no idea what determines the order. There are two physical networks and two different subnets. The second network is pretty much isolated. No gateway is defined and there is no routing between the two subnets either externally or on the server. On Thu, Jul 7, 2011 at 1:12 PM, Michael B.

I have a site that wasn't set up by me that I manage. It has Exchange 2007 running on server 2003. The server is connected to two physical networks. There is the "main" network and then a second network that is used to connect some internal equipment. One NIC connects to the "main" network and the second NIC connects to the internal network. There are no gateways or routes defined on the second network. There is no routing between the networks. The DNS has two records for "server1" . One is the main network with say 10.10.10.10 and another for the internal network say 10.20.20.20. I was doing some undelivered mail troubleshooting this morning and I noticed that in mail headers Exchange includes the server address of the internal network and not the server IP address of the main network. How does Exchange decide which address to use in the above and can it be set?
