FREQUENTLY ASKED QUESTIONS

Can't find the answer you're looking for? Ping me on X/@jro7 or email.

Why would you need a DMARC record? Implementing a DMARC record is essential for
securing your domain and protecting your organization and users from email-based
threats. It helps ensure email authentication, prevents spoofing and phishing,
improves email deliverability, provides visibility and reporting, protects your
brand reputation, and allows for policy enforcement. By implementing a DMARC
record, you can enhance your overall email security posture and build trust in
your communications.
How to setup DMARC? You add a TXT DNS record to your domain, with the name
_dmarc and the value which you copy from above. So for example if you copy the
value v=DMARC1; p=none; you would add a TXT record with the:
name: _dmarc.yourdomain.com and
value: v=DMARC1; p=none;.
Why is DMARC suddenly so "hot"? Google, Yahoo, and other major email providers
have strongly endorsed DMARC. They have implemented policies that favor emails
from domains with DMARC records, improving deliverability for compliant senders
and enhancing security for their users. So if you rely on emails getting
delivered, you should probably add a DMARC record to your domain.
How to monitor my DMARC record? Setting up your DMARC record once is fun, but
monitoring it is even more fun. You can use Mailhardener to validate your DMARC
record and get reports. This will help pinpoint potential issues and delivery
problems.
