Can a stranger send
mail as your domain?

This page reads your live DNS from your own browser and answers in about four seconds. It expands every include: in your SPF record to get the real DNS lookup count — the number that decides whether your record works at all — rather than counting lines like most checkers do.

Apex domain. A pasted URL or email address works too — it gets trimmed down.

If you would rather not touch DNS yourself: $19, one domain, same day.

I take the output above, work out the correct records for your actual mail setup — including flattening an over-limit SPF without breaking your senders — and send you the exact values to paste, the order to apply them so you do not black-hole your own mail on day one, and a dig command to verify each step.

You pay after the records are in your hands and you have checked them. If they are wrong, pay nothing.

Who sends your mail matters more than what the checker found. One line is enough.
