I'm using Exchange 2007s send connector with a smart host. Our existing ISP used port 25 with no auhentication but we have now had to move service providers and have been given port 465 and SSL with authentication to use.
I have used set-sendconnector to change the port to 465 and have entered the authentication under the smart host settings however when you send emails they just queue with no obvious error message of why this is occuring.
As a test i have installed Windows Live Mail on the same server and entered the same pop and smtp information which allows this to send and receive ok.
Can anyone offer advise to what i may have missed in the setup?
