Fair point.
What I'm actually proposing, though, is that a new, stricter, specification
for Recieved(etc) be written as an interim measure which would not obsolete
2822 but compliment it. Eventually the next iteration of 822 et al could
obsolete our rfc and adopt the chnage.
So.. an MTA could continue to implement rfc2822, and optionally implement
our new RFC by constructing the headers with as much optional information
as is incuded in 2822 and required by us.
I think that most MTA's already validate and publish some degree of
optional information in received headers, and some of them can have this
behaviour changed by config alone.
