Amazon SES MailFromDomainNotVerified error encountered when sending emails through Amazon SES.

The MAIL FROM domain is not verified in the Amazon SES console.

Understanding Amazon SES

Amazon Simple Email Service (SES) is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. It is a reliable, scalable, and cost-effective service for businesses of all sizes.

Identifying the Symptom

When using Amazon SES, you might encounter the error MailFromDomainNotVerified. This error typically appears when attempting to send emails, indicating that the MAIL FROM domain is not verified.

What You Observe

Emails fail to send, and you receive an error message stating: "MailFromDomainNotVerified". This error prevents successful email delivery through SES.

Understanding the Issue

The MailFromDomainNotVerified error occurs when the domain specified in the MAIL FROM settings is not verified in Amazon SES. Verification is crucial as it confirms that you own the domain and have authorized its use for sending emails.

Why Verification is Necessary

Domain verification helps prevent email spoofing and ensures that emails are sent from legitimate sources. Without verification, SES cannot confirm the authenticity of the domain, leading to the error.

Steps to Fix the Issue

To resolve the MailFromDomainNotVerified error, follow these steps:

Step 1: Verify Your Domain

  1. Log in to the Amazon SES console.
  2. Navigate to the Domains section.
  3. Select Verify a New Domain.
  4. Enter your domain name and choose Generate DKIM Settings if required.
  5. Follow the instructions to add the provided DNS records to your domain's DNS settings.

Step 2: Update DNS Records

  1. Access your domain's DNS management console (e.g., Route 53, GoDaddy).
  2. Add the TXT record provided by Amazon SES to verify the domain.
  3. If applicable, add the CNAME records for DKIM authentication.
  4. Wait for DNS propagation, which can take up to 48 hours.

Step 3: Configure MAIL FROM Domain

  1. In the SES console, go to the Domains section.
  2. Select your verified domain and choose Set MAIL FROM Domain.
  3. Enter the subdomain you want to use as the MAIL FROM domain.
  4. Update the DNS records as instructed to configure the MAIL FROM domain.

Conclusion

By verifying your MAIL FROM domain and updating the necessary DNS records, you can resolve the MailFromDomainNotVerified error in Amazon SES. This ensures that your emails are sent successfully and securely. For more information, visit the Amazon SES Developer Guide.
