there are two type of connectors in exchange send connectors (exchange uses them to deliver email) and receive connectors (exchange uses them to receive email)

If you configure a send connector you can only specify a destination port not an originating port, if you do a receive connector you only can specify a listening port(s).

Can you please clarify what you are trying to achieve?

We have an application that sends email to our exchange server.
it has 3 options: SSL, TLS and None, all 3 of them throws errors:

example of error for SSL:

it throws error : Could not Connect to SMTP host: , port 465

you need to create a receive connector on the exchange server listening on port 465.

Is this application only sending emails to internal staff or has the exchange server the need to route the emails this application creates to the internet?

IF so you need to create a receive connector which allows relaying, but make sure you secure this connector so it only accepts connection from the application server and NOT from the internet.

Here is the Technet documentation for this

and here an How-To to do this

can this application be configured to authenticate against exchange with an username/password?

If not the only option for you is creating a externally secured-relay connector as described in my previous post.

Though , we have a Receive Connector configure this Way:
Under" Use these local IP addresses to receive mail" it is pointing to the HUB server IP address...Since we do not use Edge Server

Under " Receive mail from remote servers that have these IP addresses" it is allowing all IP addresses

Under Authentication. Only TLS is checked

Under permission Groups, only Anonymous is checked.

I am not sure if I need to check Exchange users in order to let them authenticate.
