Enhance email security using VPC endpoints with Amazon SES Manager

This article explains how to enhance email security by implementing Amazon SES Mail Manager with VPC endpoints, enabling organizations to keep sensitive email processing on private networks.

• VPC endpoints with AWS PrivateLink keep SMTP messages on private networks throughout processing
• Solution combines VPC endpoints, security groups, Secrets Manager, and AWS KMS for encryption
• Addresses compliance requirements for healthcare, financial, and government organizations
• Step-by-step implementation includes creating traffic policies, rule sets, security groups, and ingress endpoints
• Supports both on-premises and AWS-based applications via Direct Connect or VPN
• Uses port 587 for SMTP traffic (port 25 requires AWS Support exemption)
• Includes testing procedures and cleanup guidance for deployed resources

This solution enables secure email infrastructure modernization while maintaining network isolation and meeting enterprise compliance standards.
