I have a new Exchange 2013 mail server installation (no migration - completely new domain and everything). For some reason the server is not accepting mail from the Internet. My router is indicating it is forwarding SMTP packets to the Exchange
server's IP address, but nothing shows up in the message queues or users mailboxes. The event viewer is giving me no clues. No errors. This is a simple installation - one Server 2012 DC and the Exchange server. One Exchange server in
a domain environment. The receive connector looks correct. It is using port 25 and I indicated to use the IP address of the Exchange server network card. Any ideas as to how to configure the receive connector? Thanks!
