DNS Resolution Failure

Understanding Mailjet: A Powerful Email Communication API

Mailjet is a robust email communication API provider that enables businesses to send, receive, and track emails effortlessly. It offers a comprehensive suite of tools for transactional and marketing emails, ensuring reliable delivery and insightful analytics.

Identifying the Symptom: DNS Resolution Failure

When using Mailjet, you might encounter a situation where emails are not being sent or received. In the logs, you may notice errors related to DNS resolution failures. This indicates that the domain name system (DNS) is unable to resolve the domain names involved in the email transactions.

Exploring the Issue: Error Code MJ-012

The error code MJ-012 specifically points to a DNS Resolution Failure. This means that the Mailjet servers are unable to resolve the domain names necessary to route your emails correctly. This can be due to incorrect DNS settings or misconfigured domain records.

Steps to Fix the DNS Resolution Failure

Step 1: Verify DNS Settings

Ensure that your DNS settings are correctly configured. You can use online tools like What's My DNS to check the propagation of your DNS records globally.

Step 2: Check Domain Configuration

Log into your domain registrar's dashboard and verify that all necessary DNS records (such as MX, A, and TXT records) are correctly set up. Refer to Mailjet's DNS configuration guide for specific instructions.

Step 3: Use Command Line Tools

Utilize command line tools to diagnose DNS issues. For instance, you can use the nslookup command to check if your domain resolves correctly:

nslookup yourdomain.com

If the domain does not resolve, there might be an issue with your DNS provider.

Step 4: Contact Support

If the issue persists, contact Mailjet support for further assistance. They can provide insights specific to your account and help troubleshoot the problem.

Conclusion

By following these steps, you should be able to resolve the DNS Resolution Failure issue and ensure that your emails are sent and received without any hitches. Proper DNS configuration is crucial for the seamless operation of email services like Mailjet.
