[stunnel-users] EXTERNAL: How to setup stunnel für SMTP over STARTTL S (and not pure SSL)?

[Bucci, David G]

The protocol directive determines what Stunnel does during the connection setup.  "protocol = smtp" tells Stunnel to use STARTTLS semantics for the connection to the server, as described in RFC2487 (similarly to how "protocol = imap" tells it to use STARTTLS for IMAP, per RFC 2595).

Sorry, I went to the webpage  with the link you mentioned.
There I searched for STARTTLS but NO (!) occurence was found.

What does protocol (here = smtp) to do with the security handshare type (here = STARTTLS).
