And just an addendum because we are talking about it..

Maybe Hetzner can implement an egress reporting system that checks when
large SMTP traffic originates from IP(s) that do not have their PTR
records updated from the default.. When over 90 ISPs report that kind of
volume, you KNOW that something is going on..
The number in the second column is how many North American ISP(s) (of
the hundreds that provide us data) reported rate limiting those attackers.
That was from today..
That is REALLY abusive behavior that should be detectable at the source.

Historically, we see other ranges of theirs..

Of course others are even worse than Hetzner..

Yeah, Choopa..
And of course ColoCrossing..
But, it isn't up to us to tell these people what business model they
should operate, just don't cry when email providers get fed up and block
all your IP Space...
And.. on that note, closing this thread, as it isn't really what this
list is for.. Sorry folks, if I was noisy on this topic..
