Multiple domains one server and BIS

[dgrindle]

I've been using Blackberry and AT&T BIS for years and everything has worked fine. I recently had to add a new SMTP domain to my Exchange 2003 Server, and I'm having trouble setting up users with the new email domain on BIS.

Here's an example:
original SMTP domain, user@mycompany.com
New SMTP domain, user@mynewcompany.com

I can access both using OWA mail.mycompany.com/exchange or mail.mynewcompany.com/exchange

BIS will not connect to mynewcompany.com.
