[Exchange] Exchange 2007 delayed email

Hello everyone! Upgraded from exchange 2003 small business to a new domain, server 2008 x64 and exchange 2007 stand alone (no edge) and everything is working perfectly except certain emails to comcast and aol users are coming back delayed or unable to send.

550 4.4.7 queue.expired.

I double checked that our local dns server had an mx record and also double checked our address space on the send connector. The send connector currently has a * wildcard in there which should be acceptable.

Has anyone see anything like this before? Any help would be greatly appreciated. Thank you!
