Marek Salwerowicz:However, I would like to find sooner or later clients that don't use STARTTLS befoe authentication.How can I configure postfix to see differences in logs?Assuming that no sane client sends AUTH *before* sending STARTTLS, all you need is to set "smtpd_tls_loglevel=1" in main.cf (and do "postfix reload") to log the completion of the STARTTLS handhake.
Thanks a lot ! Marek
