Mail is being sent from the wrong ip address.
Posted on 2009-07-08
We have a new SBS 2008 server that was upgraded from SBS 2003. There are two IP addresses on the server 10.0.0.5 and 10.0.0.7. We are using 1 to 1 Nat on the firewall. There is a NAT rule in place to route the traffic from x.x.x.158 to 10.0.0.5. The IP address of the WAN port on the firewall is x.x.x.154.
The issue is that before the upgrade all mail was going out on x.x.x.158. Now all mail is coming from x.x.x.154 and there for the PTR look-up is failing. My guess is that the mail is being sent from the 10.0.0.7 address and not the 10.0.0.5 address.
I have tried:
Set-SendConnector "MySendConnector" -SourceIPAddress "10.0.0.5"
but that didn't do it.
Is there anyway to specify what IP address mail is going out on?
