Slow relaying of emails

 I have a Exchange 2003sp2 server running on Windows 2003 sp1 server.  I also have a CRM server running on windows 2003 sp1.  When we send mail form the CRM server, the email message takes 30-40 minutes to get recieved by any user email address internally.  If we send them to a external email adress, it takes 2-3 minutes if not quicker.  I have setup these servers in the past at least 8-10 times and have never had this type of problem before.  All servers are setup on a private network.  I have put in the ip address of the CRM server in the Allowed to Relay smtp portion of exchange.  We also have a emailfilter server running, but there is NO log of the messages ever hitting it from the crm box.
   Any ideas would be appreciated.

The first thing u should be looking for is to see WHEN  the  messages from ur CRM software or server hits the exchange server.....for that u have to enable diagnostics logging..
If i had to make a guess based on what u wrote(30-40 minutes delay) i would say it is DNS related...it is the same symphtom when it take domain users a long time to log in to the domain when starting up the desktops....and it is mainly due to the fact that  desktops are pointing to an external DNS servers...
if there was any problem with relaying or permissions ur CRM would never successed no matter how long it took...

 i checked all the desktops and servers.  I could not find anything wrong with the DNS.  I did all the standard windows tests, recusive tests, etc.  And they all came back working.  it is strating to speed up, as now they are only delayed 10-15 minutes.  very strange indeed.  When i am finished with the migration, i am going to install a new Server, making it the DNS server and the MASTER DC.  It works so i am not worried about it, i just dont know what else to do.
