rmail-forward

rmail-forward

[Eli Zaretskii]

rmail-forward lately began to format the forwarded messages weirdly.
It doesn't use the specially formatted lines delimiting the message,
that it used to use before, and instead inserts some weird looking
delimiters such as this one:

  <#part type=message/rfc822 disposition=inline raw=t>

It also inserts the forwarded message with all its headers, including
the ones created by Rmail for its own purposes, like
"X-RMAIL-ATTRIBUTES:".  Previously, I could control whether these
headers are copied to the forwarded message by toggling their display
(with `t') in the RMAIL buffer prior to using `f' to forward the
message, and the default was not to copy these headers, only those
normally shown by rmail-show-message.

Is this a bug or a feature?  If the latter, what is its purpose?

It's a feature.  When rmail-enable-mime is non-nil, message
forwarding is also done in MIME style; i.e., the forwarding
message is embeded in message/rfc822 entity of a multipart
body.  That whole work is done by
message-forward-make-body-mime of message.el which I didn't
touch.

It seems that it'a policy of message.el to include all
headers in a forwarding message except those matching with
message-forward-ignored-headers (which currently doesn't
include X-RMAIL-* but should include).  MIME-capable MUA
(includihng rmail-mime) anyway prunes the forwarded header
accoding to it's policy (e.g. rmail-ignored-headers).

Please test to forward some mail to yourself and see how
it's shown to you by rmail.  Re-forwarding that forwarded
message generates a further nested MIME message.

By the way, I first tried to use
message-forward-rmail-make-body instead of
message-forward-make-body-mime, but it signals an error
while trying to un-prune the messsage header.  It seems that
message-forward-rmail-make-body is not yet adjusted for the
new mbox-based rmail code.
