Not certain if it is ur Exchange setup or your records. Most probably the former. Go to <a href="http://www.dnsstuff.com" rel="ugc">www.dnsstuff.com</a>&nbsp;and run the DNS Report tool.<br />
<br />
If you have entered the mail domain inaccurately on the server, you should be able to correct it quickly.

I've brought our new Exchange server online and outbound mail is fine.<br />
<br />
Telnet on port 25 is fine and our mail host can successfully send in, but only by using email_address@domain_name.<wbr />domain_nam<wbr />e.com<br />
<br />
So, somehow, somewhere, I have a problem where our domain name is listed twice.<br />
<br />
Having sent out test messaged I can also see that the message header contains this same reference.<br />
<br />
I've also tested it from a remote location and had a &quot;No valid recipient&quot; and &quot;unable to relay for...&quot; message, when using our standard email_address@domain_name.<wbr />com addresses.<br />
<br />
Where do I look, and how can I fix it ?<br />
<br />
This is urgent, and I'm starting to get a bit twitchy about it.<br />
<br />
Any and all help VERY gratefully received.

Exchange 2003 receiving mail problem - domain.domain.tld instead of domain.tld

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
