#29 Wrongly parsed TXT fields, not releated to SPF/PRA
Example of how the Authentication-Results header complains about DNS reply/DNS failure:
Authentication-Results: xxxxxxxx; sender-id=softfail (DNS reply garbled) header.from=jcm@sics.se; spf=softfail (DNS failure) smtp.mfrom=jcm@sics.se
So, doing dig TXT against domain sics.se to see if there's something wrong, reveals this:
# dig TXT sics.se
; <<>> DiG 9.4.1-P1 <<>> TXT sics.se
;; global options: printcmd
;; Got answer:

There are (several) TXT RRs, but none contains either v=spf1 nor v=pra/2.0, so sid-milter should ignore these records (without complaining).
