NSA 2400 - Exchange Server Cannot Send Emails Externally

Hi All,

I was forced to prematurely remove an ESA3300 before we received its replacement. I was able to change the NAT rules to bypass the ESA and go straight to the server. I also removed the ESA's IP from Exchanges Smart Host.

I can Send emails and receive internally. I can receive external emails, but cannot send externally.

Not sure what I missed.

Any help would be greatly appreciated!

All the best,

Bill
