Hello Harald,
Am 2018-02-08 hackte Reindl Harald in die Tasten:
you miss the topic
many DNSBL's have a very short TTL and at the same time a limit of
queries froma single IP until you need to pay for the service
so if you have a inbound MX and the RBL has 2 seconds TTL and a botnet
is trying to deliver spam to you override the 2 scodn TTL with 90
seconds or whatever makes sense reduces the total amount of DNS requests
dramatically
Sounds logic.
And this feature was rejected by the Bind Developers?
i remember a response pointing out it would violate RFC's
