I'm a Hetzner customer and I've been through hell with microsoft
blacklisting. You really need to get this sorted out Mr van den Berg.
How about segregating IP ranges for outbound SMTP and managing their
reputation? At some point you either have to warn your customers that
their dedicated server may be unable to send mail to major providers
before they buy them, or control/filter/ratelimit outbound SMTP somehow.
