December 10 our server mta got the list bl.spamcop.net. The next day, has been removed. However, to this day, some mail servers reject messages with below info:
said: 554 5.7.1 Service unavailable; Client host [188.8.131.52] blocked using bl.spamcop.net
refused to talk to me: 553 Your IP address is 184.108.40.206 blackholed by bl.spamcop.net
I know this is not a problem with spamcop, only respective servers. How can I fix the current situation? Do the information about removes server from blacklist has not yet reached all servers? How much time it can take?
Sorry for my English. Thanks for response.
