Hi,
I run a recursive DNS for a Mailsystem with 10s of millions of mailboxes.
Customers are sending or receiving mail from/to national-lottery.co.uk.
national-lottery.co.uk. has a ttl of 30s on MX and NS records.
My pdns_recusors query fast enough but ns6/7.camelotinteractive.com seem
to throttle.
Would set-minimum-ttl help to lets say 7200 help in your experience...
besides the big warning in the man-page, have you used it and did it hurt?
Thank you for your insight.
Best regards
Thomas
