Rackspace SPF Setup 

SPF (Sender Policy Framework) is an email authentication protocol that helps protect your domain from spoofing and phishing by verifying which servers are allowed to send mail on your behalf. A properly configured SPF record improves your email deliverability and builds trust with recipients.

Rackspace is a managed cloud services provider that offers hosted email and Microsoft 365 solutions, often including email infrastructure that requires SPF authentication.

This guide will walk you through the steps to configure SPF for your domain when using Rackspace as your email service provider.

Rackspace SPF Requirements

Note: If you’re already using Sendmarc for SPF management, simply copy ‘include:emailsrvr.com’ and follow the steps here.

To authorize Rackspace to send emails on your domain’s behalf:

  1. Log in to your domain’s DNS dashboard.
  2. Go to the page where you can update the DNS settings on that domain.
  3. Check if a TXT record starting with v=spf1 already exists.
    • If it exists, modify the existing record to include Rackspace (details in the table below).
    • If not, create a new TXT record.

Example of an updated SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:another.net include:emailsrvr.com ~all

Example of a new SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:emailsrvr.com ~all
  1. Save your changes in the DNS control panel.

Allow up to 48 hours for DNS propagation, depending on your DNS host.
