Hi all,<br />
I want to configure Exchange 2003 to share SMTP address with other organization.<br />
The MX box is located in my instalations, so I have to forward the mails to the other organization.<br />
Im going to configure my Exchange as non-authoritative and configure a SMTP connector to mail out to recipients in the other organization. Also Im going to configure a recipient filtering.<br />
The MX box is asking LDAP queries to the other system in order to know if the recipient is local to it. If it isn´t, the MX box is going to deliver the mail to my Exchange.<br />
The problem is if I receive a mail from an invalid recipient to an invalid reciipient also (for example from u1@abc.com to u2@abc.com and both recipients don´t exist in my Exchange.<br />
What I expect to happen is:<br />
My Exchange generates a NDR sent to u1@abc.com from postmaster forwarded to the MX box, that after querying LDAP will forward to my Exchange again.<br />
So, how can avoid this loop?

Avoid problem Sharing SMTP Address between two organizations

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.

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.
