Help! I am confused as to how to properly setup the receive and send connectors in Exchange 2007. Currently anyone can send email through our mail server. We are a small company and we have Ex07 setup on a single server without an Edge server.
I have the client and default receive connectors to accept anonymous and the send is set to * with all the defaults that MS says to set for edge. Our web design guy was able to send a message through PHP via SMTP without authenticating!!
