Much of this document is borrowed from the original hack.doc from
Citadel-CP/M and Citadel-86, because many of the concepts are the same. Hats
BYTE Mnemonic Comments
A Author Name of originator of message.
-B Phone number The dialup number of the system this message
- originated on. This is optional, and is only
- defined for helping implement C86Net gateways.
D Destination Contains name of the system this message should
be sent to, for mail routing (private mail only).
-G Gateway domain This field is provided solely for the implementation
- of C86Net gateways, and holds the C86Net domain of
- the system this message originated on. Unless you're
- implementing such a gateway, there's no need to even
- bother with this field.
+E Extended ID A persistent alphanumeric Message ID used for
+ network replication. When a message arrives that
+ contains an Extended ID, any existing messages which
+ contain the same Extended ID and are *older* than this
+ message should be deleted. If there exist any messages
+ with the same Extended ID that are *newer*, then this
+ message should be dropped.
+F rFc822 address For Internet mail, this is the delivery address of the
+ message author.
H HumanNodeName Human-readable name of system message originated on.
I Original ID A 32-bit integer containing the message ID on the
system the message *originated* on.

Portability issues
