Phil,

If you send mostly via lists masses of messages not send my you/your
organisation
then p=none is the best. Ask the listserver operators to move forward.
 From what I see (DNS and your message to this list) your setup don't
looks broken.
But that's a guess based on *one* message.

Finally please notice, for discussion of DMARC related questions the
DMARC Discussion List┬╣)
may be the better place.
