SPF (Sender Policy Framework) is an email authentication protocol that prevents unauthorized senders from spoofing your domain. By verifying sending sources, SPF helps reduce spam and phishing attempts.
This guide explains how to configure SPF for Mesh Email Security, a cloud-based email relay and filtering platform that protects your outbound traffic while preserving your domain’s authentication standards.
Note: If you’re already using Sendmarc for SPF management, simply copy ‘include:spf1.emailsecurity.app’ and follow the steps here.
To authorize Mesh 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:spf1.emailsecurity.app |
Example of a new SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:spf1.emailsecurity.app |
Allow up to 48 hours for DNS propagation, depending on your DNS host.
For detailed instructions on how to update your SPF record through Sendmarc, refer to the Sendmarc SPF Setup Documentation.
