Cloud DNS Email Records

Share This Article

When using the Cloud DNS Manager to handle the DNS records for your domain, email records must be created. DNS records of the SPF, DKIM, DMARC, and PTR (also referred to as rDNS) are critical for the successful delivery of emails. This guide will show you how to put Cloud DNS email records into place.

Prerequisites

The following prerequisites will be needed to successfully add these records to the Cloud DNS Manager for your domain.

Create a CNAME record (For Mail Subdomain): [optional] add a CNAME for mail. If you’re not hosting mail on this server, you can skip this step.

Optionally, you can repeat the above with ‘mail’ to have mail.yourdomainname.com point to your VPS as a mail server.

Create a MX Record: add MX record(s)

If you are hosting mail on the VPS, you will want to make MX records that point to the server:

  1. Change the left dropdown to MX
  2. Enter @
  3. In the ‘Enter Priority Hostname’ box enter your domain or the optional subdomain CNAME from step 8
    0 mail.yourdomainname.com
  4. Click add.

If you are hosting mail elsewhere, you will enter the mx records given, e.g.

For Google Mail

or

For the Hostwinds Enterprise Email Service.

Additional records may be needed depending on your server setup.

Note that DNS propagation for the initial nameserver changes can take 12-48 hours to spread worldwide.

Adding Email-Related Records

Step 1: Log in to the Cloud Control portal. You’ll see any active cloud servers listed here.

Step 2: Click on the Network tab, then click on Domains. This will bring you to the Cloud DNS Manager.

Step 3: Click on the Actions link to the right, then click on Records. The DNS Records page will appear. Start with the SPF record needed. Select TXT in the type box, enter an @ in the next box, followed by the text entry from the SPF record. Click Add to save the changes and put the record into play.

You’ll then see the record in the list after a green “Success” banner alerts to the successful saving of the record.

Step 4: Repeat steps 2 and 3 for the DMARC record TXT, and the DKIM record TXT, making sure to apply the appropriate hostname prefix that each record type asks for.

DKIM: The standard domain host name to enter is default._domainkey

This may change based on the “selector” chosen when generating the DKIM Key-Pair for this record.

DMARC: The standard domain host to enter is _dmarc

The dmarc text data will vary based on the preferred or required level of action to be set in place by the dmarc record.
