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.
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:
Example of an updated SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:another.net include:emailsrvr.com ~all |
Example of a new SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:emailsrvr.com ~all |
Allow up to 48 hours for DNS propagation, depending on your DNS host.
