ok, that's the real problem here, because, once listed within SpamCop, it's a pain to get delisted. There's no contacts to write to, only one delisting try. After that, one'll have to wait 24 hours. As a relay host for at lot of customers, we cannot be provided with information of what blacklisted us. That is annyoing and surfing the forums, I can see that I'm not the only one who has problems. Actually, the biggest problem is some (read: many) recipients mailservers reject mails only on behalf on a check on SpamCop. SpamCop is not the only blacklist in the world and recipients should really be checking a quantity of blacklistes and cummulate the answers to give a either positive or negative reply. At last, why do all recipients answer with a 5** reply? That's bogus too in my oppinion. This should be a soft error instead.
