ASync MDN configuration for AS2
Typically external interactions with Global Mailbox occur through the global load balancer. The global load balancer then sends the requests to either of the data centers in the setup. The requests are split across data centers. However, with AS2 and ASync MDN, the MDN must be received by the data center that sent the AS2 message. The system must be properly configured to ensure that MDNs are received by the same data center that sent them.
