  I thought from my original message that you responded to that
  you understood that the "protocol" I'm referring to (above) is
  TLS (in conjunction with SMTP), not SMTP separately or in the
  absense of a TLS connection.

  Perhaps we are miscommunicating?

  I believe that either a "password" or a certicate is needed
  to establish a TLS conection and not optional.

  Are we still talking about TLS connectons?
  
  Unless there is NO authenication required, a changed authenication
  requirement is still an authenication requiring a "password" or
  certificate if it involves TLS, nonetheless.

  That valid "password" can even be blank, an email address or anything
  (including the recipient) depending on the server's valid authenication
  method.

  I'm saying that I believe the SSL/TLS or STARTTLS protocols require
  a "password" or certficate.  Are you saying that's incorrect or it's
  not necessarily so?

  I'm sure that there are those that feel that same way about passwords.

  And even so they still feel more comfortable not storing their
  passsword, even in an encryped file, on disk.

  `smtpmail-auth-credentials' use to facilitate this.

  A similiar methodology would suffice.

  Thanks.
