Split Location to Single Gone nuts

My client had a split-office condition resulting from two partners joining. They had ISDN at each location but did not WAN link the sites together. They had two Exchange 5.5 servers where technically two FQDNs. Server One was the primary name (user@maindomain.com) and it had routing connections to the other Server Two (which was BOTH user@mail.maindomain.com AND user@otherdomain.com). Apparently, the ISP helped configure the servers as well.

Both servers are completely gone and they have different ISP. I have configured a brand new Server "Three" as the only mail server (SBS 4.5 w/ Exchange 5.5 and IIS 2.0). Internet access is fine, outbound smtp mail has headers with the correct network IP and new server "three" name.

Inbound mail to user@maindomain.com does not arrive BUT mail to user@otherdomain.com does!

NSLookup shows the MX pointer at mail.maindomain.com with the correct IP address.

Is there something in DNS that the old ISP is still controlling? I'm stumped. Please post or e-mail direct at matthew.damp@sbworks.com. Thanks.

If the MX record is correctly pointed (and it sounds like it is) you likely have a configuration problem on the Exchange server.

Check the Routing tab on the Internet Mail Service properties page. It should have both domains listed and routed to.

Also, check to make sure that the SMTP addresses on the mailboxes are set to reflect the correct domain.

Routing is configured and the SMTP addresses for the individual mail boxes are correct.

I get "unable to establish SMTP connection" / time out errors on returned mail:

Unable to establish an SMTP connection. (#4.4.1)
I'm not going to try again; this message has been in the queue too long.
