They do. 95+% of the time. With that many domains, if scum open an
account, then send out spam, or someone's home system gets infected, and
they wind up sending it out, it takes a while to catch it - are you going
to argue that?

And yet Nix blocks the central mailserver.

So, google and yahoo and others should be blocked, also? Or is it only all
mailservers that are not the size of those that should all be punished?

No. Block domains.
