That is a very valid objection. From the list above for instance spamcop
is known to be very aggressive. And spamhaus recently blacklisted a big
German mail provider web.de. Though really spam was the reason you
quickly can keep out masses of valid and legal senders. So like HaJo
says, better don't blindly trust RBLs.
