The scoring helps a lot here. And because I see that it would be an
violation if I'd only block on invalid HELOS, it performs subdomain checks
of HELO and FROM domain parts. And Client IP /24 subnets. It's an attempt to
have something similiar to SPF - which blocks too much legitimate mails of
service forwarders (eg: mobile.de).

For those that don't receive mails that mean money to them it might not be
interresting. But our unknown customers would become annoyed and don't buy a
car from us - they think "simple" too.
