The sender MCA on A and the receiver MCA on B wouldn't be able to decrypt the messages. Which they need to do in order to insert xmit headers. Likewise on the hop from B to C. If this is what the vendor is expecting.

I thought AMS did not encrypt the headers, just for this purpose, so that you can route messages but won't be able to read the actual payload. Am I mistaken?

The sending end and the receiving end applications require that the required certificates for encryption/decryption are shared between the two ends and the queue manager must be AMS-capable (e.g. interceptors enabled), that's a given; the message payloads are 'sealed' in an encrypted envelope but the addressing 'headers' are not so that any intermediate, non-AMS queue managers can route but not read,which seems logical to me as otherwise the potential licence uplift would be significant as every intermediate queue manager would need to be AMS-capable - but that is just my understanding and I acknowledge I may be totally incorrect.
