"Resent-" versus "Content-Type: Message/RFC822" for forwarding
--------------------------------------------------------------

Here is a summary of the main advantages of "Resent-" versus
"Content-Type: Message/RFC822" for forwarding of mail to additional
recipients.

Advantages with "Resent-"
------------------------

It is simpler, which is of special advantage for messages forwarded
to mail servers, which have to be more complex if they are to
look into embedded content objects.

It is better supported by existing mail software, especially
mail server software and software for writing replies to
received messages replying. Some existing software wrongly
behaves as if all MIME content types except the first one are 
attachments, which only are to be shown after a special 
ommand from the user to view attachments.

Advantages with "Content-Type: Message/RFC822"
----------------------------------------------

It allows the forwarding user to add a comment before or after
the forwarded message.

It allows forwarding of forwarded messages recursively.

It allows forwarding of more than one message in a single
new message with multiple content objects.
