People who receive the list on a yahoo account would have to mark the

The focus has been on Yahoo because of a message which was posted
several years ago. I collected some statistics for an IETF mailing
list. Approximately 40% of the subscribers are using [1] DMARC; most
of then are not using Yahoo.

1. This is not the percentage of subscribers using "p=reject".
I ran some scripts on a snapshot of list of subscribers a week ago and
here is some information:
Total addresses in the whitelist: 83131
Number of unique domains: 19668
Total domains which published any valid DMARC policy: 1398
Total domains with p=reject DMARC policy: 243
Total domains with p=quarantine DMARC policy: 167
Email addresses with p=reject DMARC policy: 4773
Email addresses with p=quarantine DMARC policy: 1370
