Our e-mail appliances (McAfee) are setup with bl.spamcop.net for RBL blocking.
Works great!
But the appliances have got an internal health check, with periodically performs checks on the RBL service.
2 checks are performed:
- Check if DNS "NS" records are available for the zone "bl.spamcop.net"
- Check if DNS "A" record 127.0.0.2 is available in the zone "bl.spamcop.net"
The results are shown below:
------------------------
Appliance -> DNS Standard query NS bl.spamcop.net
DNS -> Appliance Standard query Response Server failure
Appliance -> DNS Standard query A 2.0.0.127.bl.spamcop.net
DNS -> Appliance Standard query Response A 127.0.0.2
A DIG from the appliance gives the following result:
dig bl.spamcop.net ns
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 44086
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
------------------------
For al other RBL's these checks are working ok (zen.spamhaus.org / cird.bl.mcafee.com)
Question: Why are there no NS records implemented for "bl.spamcop.net"? And can those be added?
Thanks in advance!
Kind Regards,
Spamcop RBL user
