You get reports of who out there is misusing your domain name, or if you’re misconfigured.
DMARC is a way of telling others who to complain to if the authentication mechanism breaks, or exactly what you want done if the message doesn’t pass the various checks.

So I’ve seen on here, people seem to be pushing for DMARC, but honestly what is the difference between DMARC and just using DKIM for end users. IMHO, if the message is signed with DKIM, sending reports for DMARC matters little besides knowing that someone is spamming with your domain. I’m sure this happens a lot for free domains like gmail.com<https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2fgmail.com&data=01%7c01%7cmichael.wise%40microsoft.com%7c9e66022b2007466cfccd08d38ffb7e7a%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=Z2XzmSXw1CbO5uFAVOvo3hmYqEuK7LREr2%2fnXFoH0y0%3d>, outlook.com<https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2foutlook.com&data=01%7c01%7cmichael.wise%40microsoft.com%7c9e66022b2007466cfccd08d38ffb7e7a%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=YlAgwb1qv48qUGtFO84o602IqeMz%2bLQkc3JC6VlhwzM%3d>, et al, so is there really much of an advantage? I understand the idea of sending DMARC reports sounds great, but I don’t think any of our business servers support it as of yet, but I’ll definitely be asking vendors...
