Avoid mail loops when sharing smtp address space

Hi all

I've used KB321721 to share a domain smtp address between two exchange 2003 servers in different orgs.

Because of the sharing, when a user types a non-existent email-address on that email domain, the mail loops between the two servers til' an NDR is generated.

¿Is there any way to avoid this?

Hey,

Only by making one of the servers authoritative for the domain.

You would have to configure Contacts for the recipients on the other mail server if you do choose that option. The contacts would have to have an extra SMTP address outside the authoritative domain to get mail from the authoritative server.

e.g.

Server1 - Non-Authoritative. Forwards mail to Server2 if non-local recipient. All recipients have @domain.com and @server1.domain.com

Server2 - Authoritative. Holds contacts for all recipients on Server1. Forwards mail for recipients on server1 to @server1.domain.com (generally via an SMTP connector)

Otherwise there's simply no way to know whether a message is sent to a non-existent address because neither server really claims authority.
