I've setup a new Exchange 2003 server to test. I'm trying to send an email to another person inhouse. Everytime I send a message to him, I receive an Undeliverable message back. (I have not setup his account on the exchange as of yet.) How can I route the mail to another SMTP server inhouse (Sendmail) if the user does not have an account on the local system?

I think what you need to accomplish is this XCON: Sharing SMTP Address Spaces in Exchange 2000 Server and Exchange Server 2003.

Would it be easier to force all mail thru another smtp server (linux) inbound and outbound? I assume this is accomplished thru the smarthost.

Yeah, that could work too. But since Exchange believes it's the only responsible server for your domain name you will still get a NDR. If you want to use the smarthost as an option you need to activate the "Forward all mail with unresolved recipients to host:" option and and specify the address of the sendmail machine there. Beware, this potentially opens up your machine for relay! If you allow sendmail to relay messages from your server (the default option is to allow relay from the same subnet as the sendmail server) and open up access to Exchange from the Internet you can relay messages through your servers!

A better option is to create a SMTP connector with "domain.com" as address space, force all email using that connector throught the sendmail box (Forward all mail through this connector...) and Allow messages to be relayed to these domains. That way only domain.com messages are relayed through sendmail.

Good luck! [Smile]
