9/14/2005 7:31:08 PM weird send problem

At work the big guy has a laptop and a treo 600. The exchange 2003 server  
  
will send a message from his account to anywhere using his laptop or from  
  
owa. When he sends email with the treo, using the same account, it will get  
  
to most everywhere except to certain domains..???  
  
Any ideas where to look?
