Amazon Simple Email Service (SES) is a reliable, scalable, and cost-effective email service designed to support developers and organizations with their email communication needs. This article delves into the specifics of redirecting emails using SES, including how to set up your environment, configure the necessary rules, and manage redirected emails programmatically.

Overview of Amazon SES

Amazon SES is a cloud-based email service that offers capabilities beyond simple email sending, including receiving emails. This makes it a versatile tool not only for marketing and transactional emails but also for scenarios where email processing and redirection are required.

Setting Up Email Receiving with SES

To redirect emails through Amazon SES, you first need to set up SES to receive emails. Here is a step-by-step guide to setting up your environment:

1. Verify a Domain:
   • Go to the AWS SES console.
   • In the "Identity Management" section, choose "Domains".
   • Click on "Verify a New Domain" and follow the prompts to complete the verification process.
   • Add the necessary DNS records provided by AWS to your DNS provider to validate ownership.
2. Set up Amazon SES for Receiving Emails:
   • Navigate to the SES console.
   • Under "Email Receiving", click "Rule Sets".
   • Create a new rule set if one doesn't exist.
   • Enable the rule set to start receiving emails.

Creating Receipt Rules

Receipt rules determine what actions Amazon SES will take when it receives an email. For redirecting emails, you will need to create a rule with actions to store and then forward the email.

Steps to Create a Receipt Rule

1. Specify Recipients:
   • Define the email recipients or a domain that the rule applies to.
2. Add Actions:
   • S3 Action: Store incoming messages in an S3 bucket for further processing if needed.
   • Lambda Action: Use an AWS Lambda function to process or redirect emails based on custom logic. Here's a sample Lambda function written in Python:
   • SNS Action: Notify another AWS service or system through an SNS topic.
   • Set the priority of the rule to ensure correct processing order.
   • After setting up the rules, send test emails to confirm that they are being redirected as expected.

• Logging: Enable CloudTrail or enable logging on your S3 bucket to monitor email receipt and redirection.
• Security: Implement IAM policies to regulate access to resources involved in email reception and redirection.
• Backup: Store a copy of emails in S3 before redirecting to ensure there is a backup in case of transmission issues.
• Domain Reputation: Ensure proper DKIM and SPF records are configured to maintain domain reputation.
• Cost: Consider any costs associated with using related AWS services like S3, Lambda, and SES.
• Compliance: Be aware of any legal requirements related to email handling and user privacy.
