Ok here is the setup. domain=dfwcommunication.com my dns is setup correctly and I can get resolution from all the pc's in my network. All the pc's connect to the exchange server ok and work great for internal mail and stuff. The problem lies with the external side of things. I can't send or recieve mail from the internet. I have registered an a record and an mx record with my host. That resolves correctly, when I ping the address I get request timed out??? When I try and send mail out from a client inside my network it says it went and no errors come out. I haven't recieved any mail at all to say my hotmail account? I even went into the policy section of exchange and added a %firstname.lastname@example.org to the policy and applied it. I am at a loss here guys can you help me out?
