DMARCIAN just released a new interesting write-up:
In this article, we present a guide on deploying DMARC on Cisco’s Email Security Appliance(ESA). If you believe that you already have your system’s DMARC authentication and reporting set up correctly, please take the time to read through the information and compare it to your current settings. These settings are industry best practices, and we encourage you to not diverge from them. Your ESA’s AsyncOS version should be 13+. If 14, it should be 14.0.2 or greater due to a bug in lower versions of 14. NOTES: If you don’t set this up correctly, please don’t set it up at all. If it isn’t configured correctly, you’ll pollute valid data being sent from other sources, and your DMARC data may be blacklisted by aggregators.
