Server 2008 STD R2 with Exchange 2007 SP3 - 550 5.7.1 Unable to relay

I have a brand new MS Server 2008 STD R2 (Brand new domain) with Exchange 2007 SP3 newly installed and I cannot receive e-mail. I get 550 5.7.1 Unable to relay everytime. Everything is licensed and activated. I've been googling other 550 5.7.1 Unable to relay errors on here and in the internet and cannot find an answer to the problem.

Goto Hub Transport, Accepted Domain and check if all domains are marked as Authoritative. Also check the NDR and check from which server it is bouncing back.

Check if domain is marked as an unauthorized. Check via EMC.

Nice job! That was exactly it. I am now receiving e-mail! Keep an eye out, next step is to send e-mail and then web mail/active sync...

Hello I am getting the same error, from external clients trying to send to my exchange server 2010 box "unable to relay 550 5.7.1" I have all the proper permissions in the receive connectors. Default receive connector I have anonymous users, Exchange users, Exchange servers etc, if the domain is .local this should not matter correct ?
