After migrating a test group, user, computer and mailbox to the new 2003 AD and Exch, I can receive mail from recipients on 5.5 and from the Internet. However, I cannot send to the org or the Internet. I get a 5.4.8 error: configuration error caused message to bounce between two servers or forwarded between two recipients. What am I missing on the new 2003 Exchange box? Is it "SmartHost" in SMTP or do I have to create a SMTP connector?
Any help would be greatly appreciated!
Thank you in advance for your time and knowledge.
