Thanks Linda, I figured that out, just seems odd but I'm all setup now after redoing my config.

The other thing is how to configure TLS? You'd have to have a port such as 143 for IMAP non secure bound to an IP. Then create another port for 143 to binder to the same IP using TLS. If this is the correct way to configure this then SM will show invalid (red) because you have one port duplicated against the same IP, or something to that effect. So how do you correctly configure for TLS, let's take IMAP.

IMAP non secure

IMAP SSL

IMAP TLS

For a specific mail server such as mail.domain.com

When you create the secure TLS ports, they will take the place of the non-secure ports, however, both secure and non secure will be able to connect to them.

Interesting, thank you.

My pleasure Neal!
