The problem is on your side. Your OpenDMARC milter is sending unsigned
"failure" reports for messages that actually passed authentication.
If you're going to send reports, it is best to only send failure
reports, success reports just invite trouble (mail loops, may
be considered junk mail, ...).
The notification was not signed because you haven't arranged for DKIM
signing of locally submitted mail (non_smtpd_milters and related
settings to actually sign rather verify mail that comes in via
pickup(8)).

But right below we see the message actually passed both DKIM and SPF
checks.
