  If you define some static networks to be allowed to do relaying,
  then users from those networks don't need to authenticate themselves
  to the smtp-server (for relaying).   However if a user _anywhere_
  autenticates (preferrably under TLS protection to keep the plaintext
  password secret from snoopers), then that user is allowed to relay
  independent of what possible static rulesets say.

  I almost said:


  but the smtp-authentication has not made into those texts...

  A bit of it you can find at:   doc/guides/openssl  you may also
  want to use:  doc/guides/smtpauth-login-pam-support
  (The latter you find also in  smtpserver.8)

  Ahem, I tried to mumble some more notes into  smtpserver.8,
  you can see the lattest at:
