I have the same issue. It seems there is an issue in the DNS checks. When looking up an IP Address in the web frontend it shows as not listed. But when running a dns lookup on the command line the response is not "Not found" but I get a valid DNS record in return. With google DNS: nslookup 241.195.201.138.bl.spamcop.net 126.96.36.199 Server: 188.8.131.52 Address: 184.108.40.206#53 Non-authoritative answer: Name: 241.195.201.138.bl.spamcop.net Address: 220.127.116.11 With authorized name servers nslookup 241.195.201.138.bl.spamcop.net dns4.name-services.com Server: dns4.name-services.com Address: 2604:4000:4000:0:64:98:151:2#53 Name: 241.195.201.138.bl.spamcop.net Address: 18.104.22.168 When looking up 22.214.171.124 in web frontend it shows as not listed. What ever IP address I try to lookup I always get a valid IP address in return and all mails are blocked.
