Hello again, thanks for the reply. The problem that I see to this is that if is only black-listed the real source (the first IP) of the spam messages, if a spammer uses some server to relay it through or uses a stolen account on a server, if I use SpamCop on my MTA, those messages wouldn't be rejected, am I right? May be, those cases, are few... Regards, Alvaro.
Hello, I just have a question about SpamCop. When a spam report is received, which IPs are black listed, the real source of the spam message or the relays through that message has passed? Other RBLs do the same? Only that Thanks!
