Question 1

What is a DMARC record?

Accepted Answer

A DMARC record is a TXT record in your DNS that tells receiving email servers how to handle emails that claim to be from your domain but fail authentication checks (SPF and DKIM). It also tells them where to send reports on email activity.

Question 2

Why do I need a DMARC generator?

Accepted Answer

DMARC records have a specific syntax with multiple tags. A generator simplifies the process, ensuring your record is correctly formatted. Instead of manually writing `v=DMARC1; p=none; rua=mailto:address@your.com;`, you can use a form to select your options, reducing the risk of errors that could impact your email delivery.

Question 3

What do the different DMARC tags mean?

Accepted Answer

DMARC tags include v (Version), p (Policy), rua (Aggregate Reports), ruf (Forensic Reports), pct (Percentage), and aspf/adkim (Alignment). See page for full details.

Question 4

What policy should I start with?

Accepted Answer

It is always recommended to start with a `p=none` policy. This is 'monitoring mode'. It allows you to collect DMARC reports and analyze your email traffic without affecting email delivery. Once you are confident that all your legitimate sending sources are properly authenticated, you can gradually move to `p=quarantine` and finally `p=reject` for full protection.
