# Lock down your domain records, policy, proof

Publish the records that prove your mail is yours, and check what your domain says in public.

[Open mail](https://openemail.uk/mail/inbox) [Get Started](https://openemail.uk/signup.md)[Every walkthrough](https://openemail.uk/features/in-practice.md)

yourdomain.com

yourdomain.com Records found

TXT @ Ownership

CNAME oe1.\_domainkey Signing

TXT \_dmarc Policy

MX @ Routing

Starter policy v=DMARC1; p=none

Copy each record into your DNS. The domain verifies once all of them are found.

How it works

## Running in three steps.

1. 01
   
   Add a domain
   
   Ownership, signing and routing records are generated for it, with a starter policy.
2. 02
   
   Publish the records
   
   Copy them into your DNS, or sync them in one press where supported.
3. 03
   
   Check it in public
   
   The free tools read what your domain publishes and grade what is missing.

What it runs on

## The parts doing the work.

Nothing here is a separate product. Each one is a piece of the mailbox you already have.

Multiple domains

Point several domains at one inbox, subdomains included.

acme.com acme.dev team.acme.com hey.acme.io

DMARC policy

A starter p=none record, printed to copy or written by a sync, never tightened for you.

TXT \_dmarc.acme.com

v=DMARC1; p= none; rua=…

Optional watch only
