Right now we have the firewall set to block everything except our internal
IP range while I'm testing. I'm connected to our VPN so I'm within the
range. However, when i test from Outlook, I get the error I posted and
nothing in the Postfix log.

Here is the Outlook error when testing using port 465 over SSL...

As for the Postfix log there is no entry for this test. It seems like the
connection attempt is not even happening or something. However, the
