I use those settings and the functionality works as described, and the documentation is correct.
You need to enable external authenticated relay access to your SMTP server (ie SSMTP access) in the server manager E-mail panel, under Change e-mail reception settings, and select Allow SSMTP (secure).
You also need to enable the provision of encrypted external (public) access to the POP3 & IMAP servers, (ie authentication) in the server manager panel, under E-mail Change e-mail access settings select Allow private and public (secure POP3S) and/or select Allow private and public (secure IMAPS).
You also (ie "as well as") need to do both steps referred to in the Email FAQ re
"How do I enable smtp authentication for users on the internal network"
and
"How do I disable SMTP relay for unauthenticated LAN clients"
Then you also need to reconfigure your email clients to use a secure SSL connection and port 465 for outgoing SMTP server & port 993 for incoming IMAP server.
...the "config::qpsmtpd::Authentication" db variable is incorrect, as I find out, it should read: "config::ssmtpd::Authentication"
No, it is correct in the documentation. Here's my servers settings:
