Ionos mail dkim

DKIM (DomainKeys Identified Mail) is a security protocol used to authenticate the sender of an email message. It involves adding a digital signature to the email header, which is verified by the recipient's mail server to ensure that the email has not been tampered with or spoofed.

Here's a step-by-step guide on how to set up DKIM with Ionos (1&1 Ionos) email:

Prerequisites:

  1. You have an Ionos email account (e.g., [yourname]@yourdomain.com).
  2. You have access to your Ionos control panel.
  3. You have a TXT record set up for your domain (see below).

Step 1: Create a TXT record

  1. Log in to your Ionos control panel.
  2. Go to the "DNS" section.
  3. Click on "Add DNS record" and select "TXT" as the record type.
  4. Enter the following information:
    • Host: _domainkey.yourdomain.com (replace yourdomain.com with your actual domain name).
    • Value: k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC... (this is the public key generated by Ionos).
  5. Save the changes.

Step 2: Generate a DKIM key

  1. Log in to your Ionos control panel.
  2. Go to the "Email" section.
  3. Click on "DKIM" and then "Generate DKIM key".
  4. Follow the instructions to generate a private key and public key.
  5. Note down the public key value, as you'll need it later.

Step 3: Configure DKIM in Ionos

  1. Log in to your Ionos control panel.
  2. Go to the "Email" section.
  3. Click on "DKIM" and then "Configure DKIM".
  4. Enter the public key value you generated earlier.
  5. Select the domain for which you want to enable DKIM.
  6. Click "Save" to save the changes.

Step 4: Verify DKIM

  1. Wait for 24-48 hours for the DNS changes to propagate.
  2. Check your email logs to see if DKIM is working correctly.
  3. You can also use online tools like DKIM Analyzer or Mail Tester to verify your DKIM setup.

That's it! Your Ionos email account should now be set up with DKIM.
