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:
