I used *openssl s_client -debug -starttls smtp -crlf -connect

But using msmtp, configured with TLS OFF, STARTTLS ON and AUTH ON, I get
this message: *msmtp: cannot use a secure authentication method*

you should use "tls on" and "starttls on".
tls off disables encryption at all.
"starttls on" and "starttls off" configure how is the encryption used when
"tls on" is used.
