SPF Record Checker

Is your domain SPF-protected from spammers and phishers who are likely to forge emails pretending to be from your domain? A genuine SPF record must be published in order to use SPF. Use our free SPF checker to validate the published SPF Record for your domain.

Sender Policy Framework (SPF)

Sender Policy Framework is an email authentication protocol that domain admins deploy to prevent spammers from spoofing their domain.

How SPF authentication works

SPF verifies the IP address of the sender against the alleged owner of the transmitting domain in order to validate the origin of email messages. The SPF data identifies approved email servers for outbound traffic. Target email systems check to make sure that emails come from trusted outbound email servers.

How can I add an SPF record for my third party email senders

To add SPF records for those third-party senders, Information Services must add network configuration records depending on the information provided by those third-party senders.
