We do not play games to make our outgoing messages DMARC compliant, because it would require updating our listserv license at a cost of $6,000, and our annual budget is $1,500. Mail from ISPs with a REJECT policy are delivered to our gmail addressees, but marked as potential spam. But once the user approves them future messages from a list are delivered without warnings. They are still not delivered to ISPs that respect the REJECT policy, of course. But Microsoft is not a problem either. We have solved any DMARC issues by not allowing users of ISPs with REJECT policies to post directly, although occasionally one gets through. Instead, a moderator intercepts the message and reposts it. And asks the sender to stop using Yahoo. Most have complied. Larry -- Larry Finch [email protected]
