Today we've found that our mailserver is blacklisted by Spamcop,
but neither we, nor our ISP received any reports on a spam-message listed on a webste.
Also there is no any reports on that spam-message in a Report History section of
So we had no chance to take an appropriate measures against spammers.
We're web-hosting company and spam facts from our clients happen sometimes
and we are always reacting on received spam-reports.
Also Spamcop blacklist is used on our mailserver.
But this time a mailserver's IP was blocked without any notification from SpamCop!
Sad but true Can anyone help to resolve the situation?
