Interruptions: they're everywhere.
This is the second post in a two-part series to implement DMARC controls for actively-used domains, where this post focuses on creating and reviewing/adjusting your DMARC policy and controls.
As a follow-up from my previous post about implementing DMARC controls for unused/alias domains (those not used for actively sending messages), I wanted to write a bit about how to implement basic DMARC controls for those domains actively used to send emails.
This past Friday, somewhat out of the blue, I was pinged by a friend about helping him work through implementing what I'd done to date with Certbot...with the additional twist of his own unique configuration challenges.
I'm speaking at MMS Miami Beach Edition, October 29-November 1, 2023
