If you are referring to the aggregate and failure reports that DMARC
lets you request, that's how they're supposed to work.  Log them and
move on.  If something is sending you "alarms" when it gets a report
of a DMARC failure, it's broken.

I send mail to zillions of Mailman lists with p=none and get none of
these alerts.  Whatever your problem is, p=none isn't it.  I happen to
have 184,000 DMARC aggregate reports and 77,000 DMARC failure reports
in the file so I am not unfamiliar with how they work.

Please leave the list alone.
