Here's how I test :
$ openssl s_client -connect my.mail.server:submission -starttls smtp
the logs show
Apr 18 14:18:04 messagerie postfix/smtpd[26383]: connect from
unknown[192.168.100.241]
Apr 18 14:18:04 messagerie postfix/smtpd[26383]: disconnect from

I can only see TO connections but not FROM connections and I would
like to see both
Can you show us how your logs look like when you make
a TLS connection to your server ?
