June 2017 Deliverability Industry Expert Pro Tip

Author |  Zack Aab

DMARC is a great tool, not only for securing your domain against phishers, but also for auditing and monitoring the authentication practices of any and every partner, department, and tool that uses your domain. The major ISPs will send back reports with volume, source, and authentication information of every email they have received from your domain, including subdomains!

 

Analyzing this information can be very helpful in identifying infrastructure problems you didn’t know you had. In order to do this, you simply need to add a mailbox URI to your DMARC record like so: “rua=mailto:dmarcreports@example.com”

 

Remember that this email address needs to use the same domain that holds the record, or else you have to set up “External Authorization.”

 

If you don’t have a DMARC record yet and are worried about interfering with your emails by accident, you can use “no policy” aka “report-only” record like so:
“v=DMARC1; p=none; rua=mailto:dmarcreports@example.com;”
If you have any questions about External Authorization, translating the reports, or implementing DMARC in general, you know who to call!
