libopendkim 2.1.3: dkim_reputation dnsupgrade libar

(Yes, hopefully soon to be upgraded)

Today I noticed quite a number of DKIM error messages in my mail log file.

Nov 15 21:46:43 hydrogen opendkim[3712]: 0LBY00O651PU6U00: dkim_eoh():

The corresponding messages in my MTA log file:

A second MTA/OpenDKIM combination shows the exact same error. It seems
to result in a (decent) 451 tempfail, but I'm curious about what might
cause this 'internal' error?

FYI: this same OpenDKIM signed 2500+ messages today and verified some 70
messages succesful.
