We are using 8.01 eval version and have about 11 rdns servers to query as part of the blacklist test. It seems to query the servers ok but in checking the results of 1 ip that it let through, it was found to in fact be on 127.0.0.4 from relays.osirusoft.com. When queried manually
C:\>nslookup 51.45.158.207.relays.osirusoft.com
Server: ns1.mindspring.com
Address: 207.69.188.185
Non-authoritative answer:
Name: 51.45.158.207.relays.osirusoft.com
Address: 127.0.0.4
it reponds that it is on the list. My question do these check use RDNS when asking relays for example or does it just give it a straight ip and not the reverse? Thanks
