This error is a new one for me.<br />
<br />
We have two domain names.<br />
<br />
One domain name is bouncing back, both domains are set up the same and both are accepted domain names in the exchange server.<br />
<br />
We are using exchange 2010.<br />
<br />
There is not really an error stated, which is why I have not seen this one before.<br />
<br />
The message is from postmaster@ourdomain.com<br />
<br />
Message reads<br />
<br />
&quot;This is an automatically generated Delivery Status Notification<br />
<br />
Delivery to the following recipients failed.<br />
<br />
user@ourdomain.com&quot;<br />
<br />
This is all the message gives me to work with.<br />
<br />
My thinking is, if it is coming from postmaster@ourdomain.com then the message has to be getting to our server. &nbsp;So why the bounceback?<br />

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.
