Having a problem with mail delivery for one user. &nbsp;We are using SBS 2003 &amp;&nbsp; Ex2003 and have had to continue our use of an external POP3 provider. &nbsp;Mail directed to an internal &nbsp;user that does not have an account on our SBS / &nbsp;exchange system (me@MyDomain.com) BUT does have an account on the POP3 provider system &nbsp;(me@MyDomain.com) is not being delivered to the POP3 provider. &nbsp;We instead get an NDR report. &nbsp;<br />
<br />
I cannot change his email address (me@MyDomain.com). &nbsp;A contact record results in a server bounce. I am unable to deploy OWA in the short term.<br />
<br />
How can I get the mail originating internally for this individual to be delivered to the POP3 system?

Email non-delivery in exchange 2003

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

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.
