User email not working. Admin email is working.

Using LDAP authentication. Email server uses SSL over a unique port (not 465). Mail server is Mdaemon. When I log in as the Administrator I can send a test message. I can not send a test message as a regular user. I don't even see the login attempt from the email server. It feels like maybe the user is not using the custom port number setup for the email server on the Admin side.

Just getting started here. Any help is greatly appreciated.
