3. Select Generate SPF Record.
4. Review the status, checked facts, and next actions.
5. Use the linked guide section for any issue that needs a fix.

## Topic Overview
An SPF generator helps you build a starter DNS TXT record that lists the systems allowed to send for a domain. It is useful when you know which email delivery services, mail hosts, or includes should be authorized but do not want to hand-write the record. Read [SPF](https://mailrith.com/guides/spf.md#steps) before publishing so you understand what each mechanism means.

The safest SPF record is specific and maintainable. Avoid adding every service you might use someday, avoid `+all`, and watch the lookup limit when using many includes. After generating the record, publish only one SPF TXT record for the domain, then check it with the SPF checker. Use [DMARC Alignment](https://mailrith.com/guides/dmarc-alignment.md#steps) to understand why SPF still needs an aligned domain to help DMARC.

## What the Tool Checks
- Common sender name recognition
- Exact include, ip4, ip6, a, and mx mechanisms
- Duplicate mechanism cleanup
- DNS lookup estimate
- Suggested TXT value
- Plain-English publishing guidance

## Result Behavior
The result gives a ready-to-review SPF TXT value and warns when the record may become too broad or too lookup-heavy.

## AI Agent Notes
- Use this markdown page for retrieval, summarization, and deciding which tool to recommend.
- Use the human page when the user needs to run the checker interactively.
- Do not claim the tool sends emails unless the page explicitly says it does.
- When the result mentions a server-side confirmation, explain that the browser page can show public signals but cannot complete that network check by itself.

## FAQs
### Can I publish the generated SPF record immediately?

Review it first. SPF should include only systems that really send mail for the domain. Remove old services before publishing.
### What if my domain already has SPF?

Do not add a second SPF record. Merge the new sender into the existing SPF record so the domain still has one SPF TXT record.
