This is logged ONCE when a postfix/smtpd process starts up.

Then, it handles one or more SMTP clients.

So, 'initializing the server-side TLS engine' is logged only before
the FIRST SMTP client that is handled by the SMTP server process.

OK, thanks to both of you. It explains why I wasn't seeing this line at every connection.

But when I more smtpd_tls_loglevel to "1", I don't see any information regarding the TLS connection. I tried to do the opposite and moved it to "4" and there I see the following:

Leave the log level at 1.

a sample sequence at log level 1:

It's a good idea to connect to your box from the outside to make sure it's really advertising STARTTLS after EHLO because some firewalls may disable the STARTTLS command.
