So we have the box checked to turn dmarc on for incoming mail. I'm curious what it is doing in the background though as I didn't see any documentation on it. If the sending domain has dmarc set to quarantine for example, does SM dump it to junk? If they are set to reject, how do we know about it, since presumably, it wouldn't hit the spam filters? Or maybe it does hit the spam filters. Anyone have an example of a log entry of dmarc rejecting or quarantining an item?
