MX records on Email Domain

AWS can help you manage MX records for your email domain through several services, primarily Amazon Simple Email Service (SES) and Amazon Route 53.

For email receiving with Amazon SES, you need to add an MX record to your domain's DNS configuration. This MX record directs incoming emails to Amazon SES for processing. The MX record should point to the SES endpoint in the AWS Region where you're using the service. For example, if you're using the US West (Oregon) region, your MX record would look like this:

10 inbound-smtp.us-west-2.amazonaws.com

The '10' at the beginning represents the priority of the mail server.

If you're using Amazon Route 53 for your DNS management, you can easily add this MX record through the Route 53 console. Route 53 supports MX records and allows you to specify both the priority and the domain name of your mail server.

It's important to note that when setting up MX records, you should use only one email service for your domain to avoid delivery issues. If you're transitioning to AWS services from another provider, make sure to remove any old MX records and use only the AWS-related MX record.

Remember that after making changes to your MX records, it may take up to 24 hours for DNS propagation to complete. During this time, you might experience some inconsistencies in email delivery.

By leveraging AWS services for your email domain's MX records, you can benefit from the scalability, reliability, and advanced features offered by Amazon SES for managing your incoming emails.
