SPF Record Generator

Build a simple SPF record with ip4, ip6, include, and final policy.

Before publishing

A domain should publish only one SPF record. Also check the ten DNS-lookup limit before moving to a strict -all policy.

Practical guidance

Use the result with confidence

Recommended workflow

  1. Use a non-sensitive representative input for building an SPF record.
  2. Run the operation and review the result before copying or exporting it.
  3. Validate the output in the target application or environment before relying on it.

What to verify

  • Confirm the scope, units and input values before interpreting the output.
  • Separate the observed result from the operational decision that follows from it.
  • Validate the conclusion against the real target system, logs or configuration before changing production.
FAQ

Questions about this tool

Can I publish the generated record as-is?

Review the sending domains, selectors, include mechanisms and policy level first. A syntactically valid record can still be wrong for your mail flow.

How do I validate the DNS record after publishing it?

Wait for DNS propagation, query the exact TXT name and verify that only the intended effective policy is returned.

Can a wrong record interrupt mail delivery?

Yes. SPF, DKIM and especially DMARC policy changes can affect authentication and delivery, so deploy progressively and monitor reports.
