Amazon SES Mail Manager added optional support for TLS and mutual certificate-based authentication (mTLS) at its Ingress Endpoint, enabling compatibility with legacy mail systems while enhancing security. This update allows organizations to maintain stronger security controls without disrupting existing infrastructure.
Additionally, two new rule actions—Invoke Lambda function and Bounce—enable greater email processing flexibility and compliance. Invoke Lambda integrates AWS Lambda functions directly into email workflows, while Bounce generates RFC-compliant SMTP responses. These enhancements are now available in nearly all AWS regions except select Middle East locations.
