I have a customer having some DNS issues. They have done some research
regarding some DNS timeout errors they saw with Verizon's sender verify
looking up their MX records. What they have discovered is their current
DNS service has a 1% failure/timeout rate. They are exploring other
vendors (UltraDNS for one), but need an estimate of the number of DNS
queries for accurate pricing to put together a ROI argument for the
switch.
I have no IDEA if this can be determined, but what is a good estimate of
the number of DNS queries generated from sending an email?
That's not a good tack to take to figure out the answer.
Just check the logs of your current DNS server and count 'em up.
UltraDNS isn't cheap. But neither is downtime, I suppose.
