Hi,
I have Exchange 2013 CU3 installed.
I have configured a SendConnector for relaying mails to a smarthost. My problem is that I need a SSH tunnel to connect to the smarthost. So I configured a SSH port forwarding to the smarthost SMTP. So I can connect to "localhost 9925" with SMTP
and get connected to the smarthost SMTP port 25.The port 9925 is the port that is forwarded to 25. I configured localhost 9925 as smarthost in the sendconnector. I added the real smarthost address to the namespace.
But when I now try to send an email through the SendConnector the messages get stocked in the queue with the error "454 4.7.5 Certificate Validation Failure".
Can anyone help me with this problem?
