The difficult with a term like "payload" is that the definition
depends on where one is looking from. Internet email is a
layered system and the perspective depends on the layer. For
SMTP (from RFC 821 through 5321 fairly consistently), what it is
transferring ("the payload") would be the message content
And then there's "payload" as seen from the Ethernet, IP, and TCP
layers...
