AWS Transfer Family Adds Asynchronous AS2 MDN Support
📨 AWS Transfer Family now supports receiving Message Disposition Notifications (MDNs) asynchronously for messages exchanged over AS2. You can request MDNs over a separate TLS connection so partner systems with extended processing times or high latency can return dispositions independently. Transfer Family continues to support synchronous MDNs, enabling seamless migration of AS2 workflows to AWS while preserving interoperability with existing trading partners. This capability is available in the majority of AWS regions where Transfer Family is offered.
