That's easy -- you can't. DMARC policies can work well on domains whose mail is sent from a single set of fixed sources. They won't work at all on mail domains with live people who invariably send mail in all sorts of different ways that SPF and DKIM don't describe. But it's still worth publishing a DMARC record with p=none to collect the statistics. That's what I do, and I find out all sorts of interesting stuff.
