    How can I verify if TLS is working for SMTP? I can see when I connect to Dovecot via IMAP4, a TLS session is present but I don't know to configure TLS for SMTP (sending messages).

    Below is me sending an email from my server outbound to an external email address. Obviously the IMAP4 session is TLS but what about SMTP?

    Code:
