Hi,
Generally the headers you'd want to preserve depend on the level of
facilities you'd want to have in the stripped folder.
If the threads must be keeped, then Message-ID, In-Reply-To and References
have to remain in the message. Message-ID is also an excellent resource if
you want to refer somebody else to this message by a short link to its
Google repository instead of forwarding the message to him/her.
Second, if your messages contain MIME attachments you'd like to view with
helper applications, MIME-Version and Content-Type also should be kept.
Please see attached my sed script I use when saving an article from a
newsgroup. A similar script is used for mailing lists, too.
HTH
