US provider Verizon protects its customers from the rest of the world
Blacklists are actually only meant to support spam filters. But more and more they are being used against the advice of their operators to block out whole sections of the Internet by email. Now France, England, Germany and Russia have been hit – completely.
Spamcop is an abomination to me personally for a long time. Although the operator itself explicitly discouraged using the blacklist for anything other than tagging mails as possible spam so that they can be pre-filtered, admins regularly disregard this advice. Whoever sends mail from a server that has landed on Spamcop – or another blacklist – will have his mail deleted without comment or sent back with false error messages instead.
