I use powerdns recursor locally on my MX. It is designed for, targeted
at, extremely high volume query loads, e.g. ISP environments, thus
logging such failures would be useless due to the sheer volume. Think
web pages containing multiple broken/dead links, then multiply times
millions of page loads per day.
Thanks for the recommendation and thanks also for confirming that it
seems to be a widespread thing. I'll look into powerdns recursor
requirements and give it a spin.
