I have two smtp issues. &nbsp;I have a program that sends an e-mail out to a group of people when an action is done. &nbsp;It is not working so I am using telnet to see what the issue is. &nbsp;My first issue is that about a year ago we switched from olddomain.com to newdomain.com. &nbsp;so now when I telnet and do mail from:user@newdomain.com it comes back with authenticated user@olddomain.com &nbsp;and when I try to send it says unable to relay. &nbsp;I am pretty sure the issue is that it views me as olddomain.com how do I change that to help me relay to outside mail. &nbsp;Inside mail works fine becuase I allow olddomain to work in my network.
