DomainKeys Identified Mail (DKIM) is an anti-tamper protocol that ensures your mail remains secure in transit. DKIM uses digital signatures to check that the email was sent by a specific domain. Set up DKIM manually on your Mandrill account to start signing your outbound emails with DKIM  keys.

Steps to set up DKIM on Mandrill

  1. Before you can enable DKIM signatures on Mandrill, you will need to add your Domain Name to Mandrill.
  2. Login to your Mandrill account and under ‘Settings’, go to ‘Domains’.
  3. After entering your Domain name, click on ‘Add’.

  4. After adding your domain name, click on ‘View DKIM settings’. You will see the DNS records that you need to publish in your DNS management console.
    Mandrill._domainkey.yourdomain.comv=DKIM1; k=rsa; p= (your unique DKIM key ) 
  5. Publish the DNS records and wait for up to 48 hours for the changes to take effect. 
  6. Click on the ‘Test DNS Settings’ button in your DNS management console and check for a verification mark against your record. 

Check your DKIM record using EmailAuth’s free DKIM validator tool.

Enterprise provenance

Why top financial institutions and governments retired their email security dashboards.

Traditional email authentication platforms sell you a dashboard and ask your engineers to do the labour. In high-stakes environments, manual oversight means delayed enforcement, configuration drift and unmonitored shadow domains.

EmailAuth is the agentic email provenance platform. Our agents enforce p=reject, keep third-party senders aligned and move your domains to full RFC 9989 compliance, the new DMARC standard,, with human-in-the-loop auditability.
