DKIM (DomainKeys Identified Mail) is a method of authenticating the sender of an email message. It is a way to verify that an email message comes from a legitimate sender and has not been tampered with during transmission.

Here's how DKIM works:

  1. The sender's email server generates a digital signature for the email message using a private key.
  2. The digital signature is added to the email message as a header.
  3. The recipient's email server verifies the digital signature by using the public key associated with the sender's domain.
  4. If the digital signature is valid, the recipient's email server knows that the email message comes from a legitimate sender and has not been tampered with.

Ionos is a cloud-based email service that offers DKIM authentication as part of its security features. Here's how to set up DKIM on Ionos:

Step 1: Generate a public and private key pair

You can generate a public and private key pair using a tool like OpenSSL. You'll need to create a private key file (e.g., dkim-private.key) and a public key file (e.g., dkim-public.key).

Step 2: Configure your Ionos email account

Log in to your Ionos email account and go to the "Settings" or "Domain" section. Look for the "DKIM" or "DomainKeys" setting and follow the instructions to enable DKIM.

Step 3: Add the public key to your DNS records

You'll need to add a TXT record to your DNS settings that contains the public key. The format of the TXT record should be:

"dkim._domainkey.<your-domain>. IN TXT \"v=DKIM1; k=rsa; p=<public-key>"

Replace <your-domain> with your actual domain name and <public-key> with the contents of your public key file.

Step 4: Configure your email client

Once you've set up DKIM on your Ionos email account and added the public key to your DNS records, you'll need to configure your email client to use the private key to sign your emails. The exact steps will depend on your email client and operating system.

Benefits of using DKIM on Ionos

Using DKIM on Ionos can help prevent spam and phishing attacks by verifying the authenticity of email messages. It can also help improve deliverability and reduce the risk of your emails being flagged as spam. Additionally, DKIM can help you comply with email authentication standards and regulations.
