Messenger uses RFC2487 "STARTTLS" for SSL over SMTP. It basically means that a supporting SMTP server sends a "250-STARTTLS", and the supporting SMTP client sends a "STARTTLS", and then all further traffic is negotiated securely. > My question is if there is a way to configure sendmail to support SSL or > if stunnel can detect clients intention to use or not SSL and then act > just passing the message foward to sendmail (client not using SSL) or do > it's regular job adding SSL before passing it to sendmail. Look at stunnel's "-n smtp" or sendmail-tls (find it on freshmeat), and you might have more luck than I've had.
