No-one, anywhere, can send mail *from a barlaeus.nl address* (MAIL FROM:
) without SASL authenticating. Furthermore, he can't
even authenticate without doing a STARTTLS first (try it yourself).
Anyone from any other address can send mail to - as
long as he isn't in our block lists or gets blocked by any of our
carefully chosen RBLs.
