Rackspace DKIM Setup

Rackspace DKIM Requirements

Step 1: Access the Cloud Office Control Panel

1. Log in to the Rackspace Cloud Office Control Panel

2. On the Home page, go to the Domains section

3. Click on the Sender Authentication (DKIM) link

Step 2: Enable DKIM for Your Domain

1. On the DKIM page, select the domain you want to configure

2. Click Enable DKIM

Step 3: Configure DNS Based on Your DNS Host

If Rackspace Manages Your DNS

DKIM will be enabled automatically—no further action is required.

If You Use an External DNS Provider

1. Rackspace will provide a DNS key and value to be added as a TXT record in your DNS

2. Log in to your external DNS provider (e.g., Cloudflare, GoDaddy or Sendmarc). If you’re using Sendmarc, you can add the keys there.

3. Add the provided DKIM TXT record to your DNS settings

 Be sure to use the exact name and value provided by Rackspace.

Step 4: Verify the DKIM Record

Once you’ve added the TXT record:

1. Return to the Sender Authentication (DKIM) page in Rackspace

2. Click Verify TXT Record

3. Rackspace will check for DNS propagation and validate the record

If the validation fails, an error message will guide you to correct the issue.

Once verified, DKIM will be active and all new outgoing emails from your domain will be signed using the new DKIM key.
