Hi. We're running the later SM version on a Windows server. We changed the IP address. Incoming email is fine. Outbound fails binding to other servers (I've tested MS, Yahoo, Gmail). There's nothing descriptive in the SMTP log. In the Delivery Log a sample of what I get:

"22:24:54.249 [06610003] Binding to local IP ##.250.186.44 (Id: 47)

22:24:54.249 [06610003] Binding to local IP ##.250.186.44 failed.

22:25:14.249 [06610003] Timeout connecting to 67.195.204.72 (Id: 47)

22:25:14.249 [06610003] Previous connection attempt failed. Attempting again with primary local ip"

I believe the bindings have been set correctly in Settings-->Bindings-->Ports. 

The local IP shown though is the old server IP, not the new, could this be what the issue is? If so, where else is the IP address updatedable in SM? I can't find any other setting than in the Bindings and:

On the Manage-->Domains-->Options I see Outbound IPv4 but it says, "Outbound IPv4 has been set in system protocol settings, so this value will be ignored."
