I try to use TLS for outgoing email but it doesn't worked.
(TLS without user authentication)
Windows Server 2008 R2
NPrinting -> TLS -> SMTP Server => not working
NPrinting -> without TLS -> SMTP Server => working
with local SMTP-Relay
NPrinting -> without TLS -> local SMTP-Relay -> TLS -> SMTP Server => working
Do I have more to configure on the NPrinting Server instead the TLS checkbox on the email settings?
