The command M-d
(mh-redistribute) is similar in function to
forwarding mail, but it does not allow you to edit the message,
nor does it add your name to the ‘From:’ header field. It appears to the
recipient as if the message had come from the original sender.
When you run this command, you are prompted for the
recipients.
For more information on redistributing
messages, see dist(1).
Also investigate the command e
(mh-edit-again) for another way to redistribute
messages (see Editing
Again).
The option mh-redist-full-contents-flag must be
turned on if dist1 requires the whole letter for
redistribution, which is the case if send2 is compiled with the
berk option (which many people abhor). If
you find that MH will not allow you to redistribute a message
that has been redistributed before, turn off this option.
The hook mh-annotate-msg-hook is run after
annotating the message and scan line (see Sending Mail).
