Subject: Re: Ack Message Payload??

A few thoughts on ACKs (in brief):
1. I supposing in this scope we can forget about delivery notification and non-delivery notification delivered by Internet.
2. A first 'end-receiver' ACK/NAK is called here and there 'Delivery Acknowledgment'. On X.400 compliant systems, it is a message
generated by the Message Store or the User Application when the end-receiver pre-processing (possibly not directly connected to
Internet) fetches or receives the message.
3. 2nd ACK in the sequence is a pre-processing ACK/NAK indicating that the message is of sufficient quality to be queued for
4. 3rd ACK in the sequence is a processing ACK indicating that the message has been successfully processed.

All ACK/NAKs should ideally be made non-repudiatable through signature of its content+original message.
NAKS should preferably contain standard enumeration of reason for failure, textual explanation on top where helpful, help on how the
problem could be fixed (e.g. which missing parameter), a pointer to a URL for further help, and next expected further action by
original sender.

Hope this helps,
