Configure the client to onnect to port 465 instead of 578.
With Postfix, uncomment the smtps(submissions) service in the Postfix
master.cf file. It should have the same "-o" options lines as the
submission service, plus a line that says "-o smtpd_tls_wrappermode=yes".
Then execute the command "postfix reload".
You may need to open port 465 with a firewall rule.

Changed email user config for testing in Thunderbird from port 578 to 465, and from
"STARTTLS" to "SSL/TLS". Sending from Thunderbird works at once.
You can leave both services running.
587/submission will use (explicit) STARTTLS, port 465/smtps (implicit) SSL/TLS
- different MUAs often call those protocols differently.
Sending from NVR still fails, new msgs in log:

authentication mechanism
your sasl server does not support LOGIN authentication mechanism.
with dovecot, you need to set up in dovecot config e.g.:
auth_mechanisms = plain login
and with cyrus sasl, your smtpd config needs e.g.:
mech_list: PLAIN LOGIN
THANK YOU VERY MUCH, Matus and Wietse,
in fact it was the missing "LOGIN" option in dovecot's auth settings, was "auth_mechanisms =
plain" and now with "auth_mechanisms = plain login" everything works fine.
Kind regards,
Michael
