If everyone always signed and encrypted their ASx messages, requested signed MDNs and used SSL encryption when transporting ASx messages there would still be plenty of options to configure. However, almost every element discussed so far is really an optional element. Specifically, the following configuration items are among those considered optional in the ASx specifications. (You can probably guess - hint: "Y" - what the best practice values are.)

  • Sign message? (Y/N)
  • Encrypt message? (Y/N)
  • Request MDN? (Y/N)
  • If requested, request a signed MDN? (Y/N)
  • Use SSL transport encryption while sending the message? (Y/N)
  • Use SSL transport encryption while sending the MDN? (Y/N)
