Hint: Check your DMARC or create a new policy.

How to use the lookup Wizard?
  1. Insert a Domain name above, and click on the Submit button.
  2. Click on "Start DMARC Wizard" button if it is a new record, otherwise the wizard will appear under your DMARC record description and validation form.
  3. Set your value for each tag you choose.
  4. When you’re done, click the "Submit" button, copy your record, then publish it to your DNS (Domain Name System). You will have to wait for your DNS to synchronize with other servers, then you can verify your new/updated DMARC record.

DMARC FAQ

What is DMARC?

DMARC stands for "Domain-based Message Authentication, Reporting & Conformance", a protocol used to validate email, policy and reporting. It prevents email spoofing from fraudulent emails who uses forged sender address.

How does DMARC work?

DMARC was created to work with two existing frameworks to indicate that the messages sender are protected by SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), and tells the receiver of the message what to do with it in case both of those authentication methods didn’t pass, then the email server of the receiver will have the options to sending it to junk, quarantine or reject the message. DMARC also provides a way for the receiver to report back to the sender if the messages pass or fail evaluation or both.

DMARC policy DNS record would look something like this:

"v=DMARC1; pct=100; fo=1; ruf=mailto:report@bahv.net; rua=mailto:report@bahv.net; p=reject; sp=reject; adkim=s; aspf=s;"

Example of coming "Pass Aggregate Report" to our Domain, would look like this: Pass Report

Example of coming "Failed Aggregate Report" (Forged email) to our Domain, would look like this : Report

Who can use DMARC?

DMARC is available and free to anyone that have a Domain name and an access to a DNS server. It's available with no licensing, any interested party is free to implement it.

How to generate a DMARC policy record?

Enter your domain name above and click on the submit button to generate a new DMARC record, or our wizard will show your DMARC policies record in detail and will validate and verify each tag and value. You can also refer to our reference page that describes each tag in detail.
