Hi,

I am not wanting to modify the mail flow from 2003. &nbsp;I need to change the route of mail that leaves E2K10 going to E2K3.

I am not wanting to modify the mail flow from 2003.  I need to change the route of mail that leaves E2K10 going to E2K3.

<div class="content wysiwyg-content">
We are in the preliminary steps of migrating from Exchange 2003 to Exchange 2010. &nbsp;<br />
<br />
We have one Exchange 2003 server, one Exchange 2007 server, and one Exchange 2010 server.<br />
<br />
The Exchange 2003/2010 need to share a namespace of contoso.com.<br />
<br />
When we send from Exchange 2003 to Exchange 2010, the mail flows directly from E2K3 to E2K10.<br />
when we send from Exchange 2010 to Exchange 2003, the mail flows from E2K10 to E2K7 to E2K3.<br />
<br />
How can we stop mail from flowing through E2K7 from E2K10?

Exchange 2003, Exchange 2007, and Exchange 2010 Co-Existence

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.

Email Servers

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.

Internet / Email Software

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.
