822 specifies one mechanism, namely Resent-* fields:
Resent-From: God@heaven.af.mil
Resent-To: angels@heaven.af.mil
Resent-Subject: take care of this guy, willya?
From: spamking@cyperpromo.com
To: God@heaven.af.mil
Subject: MAKE MONEY FAST
A once-in-a-lifetime opportunity!
This format effectively splices the new recipient into
the old recipient list.
Any 822 reader has immediate access to the original message.
A reader that knows about Resent-* fields could
provide a separate display of those fields,
without the Resent- prefix,
to show how the message was forwarded.
The new recipient might forward the message to someone else. 822bis allows multiple batches of Resent-* fields, treated the same way as Received fields: each new Resent-* field is added to the top of the message.
I recommend against using the Resent-* mechanism. For mailing lists it conveys no useful information. For manual forwarding it runs into practical problems: if the original Received fields are not stripped then the message often bumps into MTA Received-line limits; if the original Received fields are stripped then useful information has been lost. Furthermore, many users never see the Resent-* fields and are surprised to receive messages that were not addressed to them.
