How to Configure DKIM for Mandrill on Amazon’s Route 53

In this post, we’ll walk you through the steps to configure DomainKeys Identified Mail (DKIM) for Mandrill on Amazon’s Route 53. This topic is essential for data scientists and software engineers who want to ensure secure email delivery and prevent email spoofing.

What is DKIM?

DKIM is an email authentication method that allows the receiver to check if the email was indeed sent and authorized by the owner of that domain. This is achieved by adding a digital signature to the headers of the email.

What is Mandrill?

Mandrill is a transactional email platform by MailChimp. It’s widely used for sending data-driven emails, like e-commerce or personalized one-to-one messages.

What is Amazon Route 53?

Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service by Amazon Web Services (AWS). It’s designed to give developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications.

Now, let’s dive into the steps on how to configure DKIM for Mandrill on Amazon’s Route 53.

Step 1: Create a Mandrill Account and Setup a Sending Domain

First, you need to create a Mandrill account and set up a sending domain.

1. Navigate to the Settings page from the Mandrill dashboard.
2. Click Add a Domain under the Domains section.
3. Enter your domain name and click Add.

Step 2: Enable DKIM for Your Domain in Mandrill

After setting up your domain, you need to enable DKIM.

1. Click on the domain you added.
2. Click on the DKIM tab.
3. Click Enable DKIM.

Mandrill will generate a DKIM record in the form of a subdomain (mandrill._domainkey.YOURDOMAIN) and a public key.

Step 3: Set Up the DKIM Record in Amazon Route 53

Next, you need to set up the DKIM record in Amazon Route 53.

1. Log in to your AWS Management Console.
2. Navigate to the Route 53 service.
3. Select the hosted zone for your domain.
4. Click Create Record Set.
5. In the Name field, enter mandrill._domainkey.YOURDOMAIN.
6. In the Type dropdown, select TXT.
7. In the Value field, enter the public key provided by Mandrill, enclosed in quote marks (""). It should look something like this: "v=DKIM1; k=rsa; p=MIGfM...DAQAB".
8. Click Create.

Step 4: Verify Your DKIM Settings

After setting up the DKIM record, it’s time to verify your settings.

1. Return to your Mandrill account.
2. Navigate to the Domains section under Settings.
3. Click on your domain.
4. Click the Test DKIM button.

If your settings are correct, you will see a verification message. If not, review your settings and try again.

Remember, DNS propagation can take up to 48 hours, so you might have to wait a while before your changes take effect.
