Spoofing protection (DMARC)
Is there a valid DMARC record, and how strict is the policy?
Free domain check
Is your domain protected against forged emails?
The domain check reads your domain’s public DNS records and shows in seconds where the gaps are – no sign-up.
- Result instantly, with a grade from A to F
- No sign-up and no credit card
- Public DNS records only
Free domain check
Is your company address protected?
Enter your domain or your email address. You see the result right here, with a traffic light and a grade from A to F.
You opened a link to a result. The check only starts when you click, always with the current state.
Privacy: if you enter an email address, we transmit only the domain; the part before the @ never leaves your browser. We use the domain only for this check of public DNS records and do not store it in plain text; we do not store the result. We store your IP address only as a checksum and for at most one day to curb abuse.
The quick check is based on public DNS data at the time of the query and does not replace a full review; no warranty.
Keep an eye on it continuously instead of checking once:

What happens next
- Your email program opens a prepared request with your domain. Add your name and send it.
- We get back to you and discuss with you or your IT partner which records (SPF, DKIM, DMARC) are needed and what the setup costs.
- The setup needs access to the DNS management of your domain. We agree the handover with you – please never send us passwords by email.
- If you wish, DomainRadar then monitors your domain continuously and alerts you when something changes.
No email program opens? Write to us with your domain at info@domainradar.ch.
Good to know: this protection stops anyone forging exactly your domain. Against look-alike addresses, always confirm payment changes by phone.

What is checked?
The domain check examines five areas. Each area gets a traffic light and a short sentence; expand the details if you want.
Authorised senders (SPF)
Is there exactly one valid SPF record, and does it stay under the 10-lookup limit?
Digital signature (DKIM)
Can we find a DKIM key under the usual names, and is it long enough?
Mail servers and DNS
Are mail servers (MX) and name servers set up correctly?
Encrypted delivery (MTA-STS, TLS-RPT)
Are MTA-STS and TLS-RPT set up so emails arrive encrypted?
Blacklists, TLS certificates and the DMARC reports are only checked by the ongoing monitoring subscription – they are not part of the quick check.
What does the grade mean?
Every domain starts with 100 points. Each finding deducts points depending on severity, at most 40 per area. The grade follows from the points.
The traffic light above the grade sums up how urgent action is: red means your domain can be forged; yellow means there are individual gaps; green means basic protection is in place.
| Grade | Points | Meaning |
|---|---|---|
| A | 90–100 | Very well set up, at most minor details. |
| B | 80–89 | Good, a few points could be improved. |
| C | 70–79 | Basic protection in place, but with gaps. |
| D | 60–69 | Clear gaps, forgery is partly possible. |
| E | 50–59 | Important records are missing or faulty. |
| F | 0–49 | Hardly any protection: your domain can easily be forged. |
The grade only assesses your domain’s settings at the time of the check. It says nothing about the security of your mailboxes and does not replace a full assessment.
Questions about the domain check
Is the domain check really free?
Yes. You need neither an account nor a credit card, and you see the result straight away on this page.
What happens to what I enter?
If you enter an email address, we only transmit the domain behind it. We don’t store it in plain text; the result is cached for at most 10 minutes.
Why does it say “No clear result”?
Then not all records could be queried in time. Check again in a few minutes; freshly changed records sometimes take a little time before they are visible everywhere.
What is the difference to the subscription monitoring?
The domain check is a snapshot. The monitoring checks continuously, evaluates the DMARC reports, checks blacklists and certificates, and sends you an alert when something changes.
Does a good grade protect against CEO fraud?
Only partly. A good grade means no one can forge your exact domain. Against similar domains and hacked mailboxes, a call-back and the two-person rule help.
