Ive put an Exchange 2013 intallation in 3 weeks ago. The setup is all on one server which shares AD and DNS. There is a split domain scenario with .local and .com in the internal DNS. Messages tend to send out instantly but outside mail takes awhile. We had to move the zone file to go daddy a week ago ant the problems have increased. The MX record is set to * and associated to the WAN ip of the server. Is there anyway to test for incorrectness or optimize the server for quicker reception of mail? I tried adding an SPR record. Also we are getting tons of spam now. Is the internal filter in Exchange sufficient. Any help would be a life saver.
