All external mail is being queued after public IP change
I have just changed my public IP address to a new IP in a different subnet range. I have made all changes to my NAT policies, Firewall settings and DNS records. We use Postini so I didn't need to change the MX records.
I made these changes about 9.5 hours ago, and at this time everything is resolving properly, all my external services like OWA, mobile phone syncing, ping are working just fine. The issue is All the mail outgoing and incoming is sitting in the queue. The errors on each queue is "the remote server did not respond" Any help would be greatly appreciated

OK I finally found the setting for the inbound delivery manager. I am still not able to send mail externally though. Can you help with that? I setup the re-injection host IP, is there something else I need to do>
ASKER
Inbound is working now but outbound is still not working. Can you assist?

Ok I have checked the SMTP settings, I am assuming they should be the same since no changes were made to server itself its an Exchange server, and I don't see any settings that would be along the lines of what is the public ip of the server. At least I never had to set that up before.
Does the EHLO string the server issues still match the rDNS belonging to its new public IP?
ASKER
I opened a telnet session to the public IP, and issue EHLO. I got a response with the proper IP, so I assume that means yes?

Thanks so much for helping the outbound traffic needed a static route to have the SMTP traffic show it was coming from the proper IP address.
You're quite welcome. I'm glad I could help.
