If you copy the text of one of your rejected messages, create a new email via Gmail/Yahoo/Hotmail/etc., paste in your copied text, and send the message to the problem domain, is the behavior the same or different?

I have been told that header information could be the culprit but i have no clue as how to configure the header information on the Exchange server. &nbsp;If you could instruct on how to access that part would be very helpful. &nbsp;I've tried sending the same msg HTML and Plain txt formats. &nbsp;The cut and paste from my MSN account goes through just fine, no NDR from my msn account.

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

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.
