Frequently asked questions

How do I enable/update DMARC for my domain?

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. DMARC is used in combination with SPF and DKIM and provides instructions for what the recipient's mail server should do with e-mail messages with a sender address on your domain that does not validate neither SPF nor DKIM.

There are 3 main settings for the type of DMARC policy you can choose:

• None = E-mail messages should be received anyway (p=none)
• Normal = E-mail messages should be quarantined, i.e. typically placed in the spam folder (p=quarantine)
• String = E-mail messages should be rejected (p=reject)

In addition, DMARC provides mechanisms to specify a number of additional options for e.g. how subdomains should be handled and whether you want daily reports with delivery status (for advanced users).

If you use Domainnameshop as your e-mail provider, we have set up a basic DMARC entry for your domain:

"v=DMARC1; p=quarantine"

You are free to change this yourself if you wish. It can be done from "advanced settings" in the DNS control panel for your domain, by creating or changing a TXT record with the hostname _dmarc, see instructions here.

In addition, it is possible to quickly change the DMARC policy (none/quarantine/reject) in the following way:

1. Log in to the control panel at https://domainnameshop.com/login
2. Click on My Domains
3. Click on the relevant domain
4. Click on the Email tab at the top of the page
5. Click Show advanced settings
6. Scroll down the DMARC policy page and select one of the 3 predefined settings
