Message: server is on a blocklist

Already a while ago, I got an email that my server is on the blocklist of spamhaus (here the original message: “Ihr Server befindet sich aktuell auf der CBL-Blockliste von Spamhaus.”) I even wasn’t aware that blocklists exist. Neither I was aware of spamhaus. I really couldn’t get my head around this one, especially after I read that my server is possibly emitting spam. At least I managed today to make a CBL lookup at . Which was positive (Begin of the original message below).
