I tcpdump'd the dns-traffic on that box during a postmaster startup and
it's definitly trying to look up ''.kaltenbrunner.cc a lot of times.
And from what it looks like it might be getting somehow rate limited by
my ISPs recursive resolvers after doing the same query a dozens of times
and getting a "servfail" every time.
At least the timestamps seem to indicate that the responses are getting
delayed up to 10 seconds after a number of queries ...
It might be a complete shot in the dark but spoonbill worked fine on
REL_8_0_STABLE until i disabled reporting 3 month ago.
During this time the large escaping security fix/standard_strings patch
went in - could this be related in any way ?
