Hi Andrew,
The first question is what you're seeing in the aggregate feedback
reports (Dmarcian, Agari, etc. provide the means to do this). These
should be watched for a period of time (I'd suggest weeks) to ensure
that all is well before you turn on p=reject.
Also, make sure that every 'type' of email you send is sent and checked
from the reports as well.
I had to help someone recently who thought it was all OK, but they'd not
checked their occasional newsletter mailing list, which was failing
DMARC due to them not setting up their mailing list service provider
account properly. They hadn't noticed because they hadn't sent a
newsletter during the 'analysis' period.
