Thank you for answers, they all was helpful! Now it's obvious, that all this time I nevertheless was blacklisted. So, I think there was some problem with query page (http://www.spamcop.net/bl.shtml) because I'm sure, that yesterday it said "220.127.116.11 not listed in bl.spamcop.net", but my mail still has been blocked. What do you think about it?
Hi All! My server was blacklisted today on bl.spamcop.net due to a virus attack. Now we eliminated that virus, and http://www.spamcop.net/bl.shtml says that we are not blocked: "Query bl.spamcop.net - 18.104.22.168 22.214.171.124 not listed in bl.spamcop.net" But response from recipient mail server is still the same: "<<< 554 Connection from 126.96.36.199 rejected for policy reasons. Host found in DNS blacklist at bl.spamcop.net 554 5.0.0 Service unavailable" I've searched at Google groups, it seems like my server is clear, and not listed in other blacklists. Is it common problem? What can be done to solve it? Thank you.
