Hi All,
On exchange 2013 I have StartTLS adverstised on our default receive connector and that is working fine, but any other receive connectors I setup never show the StartTLS advertised when a client connects which is shown through protocol logs and using Telnet to the server on a IP that is scoped to the receiver connector with the issue. This frontend receive connector is operating on port 25.
Upon viewing the Get-receiveconnector output the AuthMechanism is set to TLS. I have also tried setting various security options on the connector but none seem to activate 250-StartTLS. Even when I set require Tls to true.
Does anyone know what is happening here, is there something i'm overlooking?
I need to send emails from our web server to external addresses via this receive connector and also need to ensure TLS is encrypting these emails.
