Thank you very much for the response. Now I actually know where I "can" set it :) The problem is, that field is blank, so I have no idea how it is getting out of the Organization.
Yes, unless you've specificially configured Exchange to forward unknown recipients to another mail host. You would typically do this when sharing SMTP namespace with foreign mail systems.
- In Exchange System Manager, expand Administrative Groups, expand Administrative Group Name, expand Servers, expand ServerName, expand Protocols, expand SMTP, and then click the corresponding SMTP virtual server.
- Right-click Default SMTP Virtual Server, and then click Properties.
Note You may have to expand SMTP Virtual Servers before you can click Default SMTP Virtual Server.
- Click the Messages tab.
- Delete any entries that are displayed in the Forward all mail with unresolved recipients to host box, and then click OK.How to share an SMTP address space in Exchange 2000 Server or in Exchange Server 2003

Subject: [ExchangeList] Exchange 2003 contact routing handled differently
I am not sure if I missed something long ago, or this is acting weird. If I have a domain catdog.com that my Exchange org is serving, shouldn't all messages sent to @catdog.org from internal MAPI clients stay within Exchange?
What is happening (Exchange 2003) ....
I have a contact jdaily with smtp address of jdaily@xxxxxxxxxx. Of course there is no Exchange mailbox for this address or it wouldn't be a contact. I would figure messages to this address would just be bounced, but instead are forwarded onto a UNIX host which forwards messages to various addresses (like a dist group).
Can anyone explain this? I am at a loss.
