One-time DNS Configuration for Cloudflare
Updated over a week ago

Sign in and Edit DNS Records

  1. Sign in to your Cloudflare account and select the domain you want to update

  2. Select the DNS section from the top menu

  3. Click the '+Add record' button


  1. Create a record with:
    -- Type: NS
    -- Name: _dmarc
    -- Nameserver:

-- TTL: 10 min (You can pick another Time To Live value, but we recommend 10 minutes

2. Click 'Save'

3. Delete any other “_dmarc” TXT records that exist on your domain.


Just as you've created an NS record for the _dmarc subdomain, now you will need to create a similar one for the _domainkey subdomain.

  1. Create another record as before with the following values.
    -- Type: NS
    -- Name: _domainkey
    -- Nameserver:
    -- TTL of 1hr


To delegate SPF to Valimail for email authentication, you'll need to add a TXT record that includes Valimail's SPF macro.

If you have an existing record that addresses SPF, backup and remove it.

1.Create another record as before with the following values.

-- Type: TXT
-- Name:

-- TTL: 10 min

-- Under Content, add: v=spf1 include:%{i}._ip.%{h}._ehlo.%{d}
