I have just setup an SBS 2011 server and configured exchange 2010. I changed dns to point at the mail server and port 25 is open in the router. I have confirmed port 25 accessibility although I dont seem to be able to telnet to the server. Mail is not being received. I have configured receiving domain and send connector. There are errors in the log id 12014 indicating a problem with the certifiacte. I need to get mail working ASAP. Any help would be appreciated.
