The SPF Email Authentication Protocol
SPF or Sender Policy Framework is an email authentication protocol that allows recipients to distinguish between the domain owner’s authorized list of senders, and unauthorized emails. Authenticating your email using SPF is the first step toward preventing domain name abuse and impersonation. To configure SPF you have to set up a DNS record. Pairing your SPF record with other email authentication DNS records can increase its efficacy against cyberattacks.
What is an SPF checker?
Our SPF checker is a software tool that helps you look up and check for errors in your SPF record. SPF checks help you to verify your domain’s SPF (Sender Policy Framework) configuration.
SPF is an email authentication protocol that enables domain owners to declare which mail servers are permitted to send emails on their domain’s behalf, hence assisting in the prevention of email spoofing and phishing.
How SPF Checker Works
An SPF checker validates a domain’s SPF record, which specifies authorized mail servers for sending emails on behalf of the domain. The SPF record checker retrieves the domain’s SPF record, parses its rules, gathers the sender’s IP address, evaluates it against the record, and determines the result as pass, fail, softfail, neutral, or SPF permerror.
Our SPF lookup tool performs the following functions:
1. Checks the existence of your published SPF record
2. Detects Multiple SPF Lookups
3. Evaluates SPF Record Validity
4. Validates IP Addresses and Domains
