Completing Exchange 2003 migration. I have migrated mailboxes and public folders. After removing IMC on 5.5 server I am unable to send email out of the organinzation, it just sits in the E2K3 Internet mail queue. I forced failure of my test email and got this NDR:
Your message did not reach some or all of the intended recipients.

This message was rejected due to the current administrative policy by the destination server. Please retry at a later time. If that fails, contact your system administrator.
I noticed that recipient policy still references the 5.5 server and org name. Do I have to completely uninstall and remove 5.5 in order to get mail flowing using the 2003 server? I was trying to avoid this so I had a point of return. It is urgent that I get this figured out since I have removed the IMC from the 5.5 server and no mail will go out, thankfully incoming still works fine.
