DKIM and DMARC set up in the admin panel, with the record ready to copy

Without SPF, DKIM and DMARC, your company's emails are more likely to land in your customer's spam folder, and it is easier for someone to run a scam in your company's name. Setting this up usually takes someone who can decipher DNS records. In the lua.email admin panel, every record comes ready to copy.

DKIM setup with active signature and the TXT record ready to copy

How it works at lua.email

  1. DKIM: Authentication → DKIM → Set up DKIM

    The panel creates the key and shows the luadkim._domainkey TXT record, ready to copy into your DNS.

  2. DMARC: start in monitoring mode

    Your domain starts out with p=none. In Edit Configuration you change the policy, the percentage and the reports.

  3. Validate

    Validate DNS checks public DNS and shows, record by record, whether it is correct. Anything missing appears ready to copy.

  4. Raise the policy step by step

    Check that every system that sends through your domain passes SPF and DKIM. Only then move to quarantine and later to reject.

Validate DNS with the result of each record (MX, SPF, DKIM and DMARC) and the guidance to fix what is missing
Validate DNS with the right records.

Good to know

  • Domain health warns you when something in your DNS changes.
  • In the panel's email logs, each message shows the DKIM, SPF and DMARC result.
  • In webmail, a message's full headers show whether the sender passed SPF, DKIM and DMARC.
  • Autodiscover in the DNS lets Outlook set itself up automatically, and the domain's autodiscover and autoconfig addresses (two A records, with the value shown in the panel) let phones and email programs find the server on their own.

Questions about DKIM and DMARC

What does DKIM do?

It signs the messages that leave your domain. The recipient checks the signature in DNS and knows the message really came from you.

Why start DMARC at p=none?

So you can first see, through the reports, whether every system that sends through your domain passes SPF and DKIM. Then the policy moves up to quarantine and reject.

Do I need an IT person?

The panel shows each record ready to copy into DNS and checks that it is correct. If you hire migration with our team (billed by the hour), we adjust the DNS with you.

Do DKIM and DMARC cost extra?

No. They come with every plan, along with the admin panel.
