Norton ConnectSafe DNS appears not to work properly for some RBL lookups..
My mail collector (POPCon) works fine if i use OpenDNS but fails some of the RBL lists if I use Norton ConnectSafe DNS.
Blacklist cbl.abuseat.org failed during testing and will not be used.
Blacklist ix.dnsbl.manitu.net failed during testing and will not be used.
Blacklist dnsbl-1.uceprotect.net failed during testing and will not be used.
Blacklist dnsbl-2.uceprotect.net failed during testing and will not be used.
Anyone got any ideas?
