NODE 51c83b5cEncrypted list software

I've had a couple of people ask to have their names added to the
encrypted list forwarder I put together. I'm soliciting feedback on
how this service should work.
Right now, it only encrypts the "body" of the message. The "headers",
which are the "From:" and "Subject:" lines, etc., are passed through
basically unchanged (except for "To:", which I change to be the person it
is going to. Maybe that's unnecessary, as I notice that the cypherpunks
list puts its own address into "To:", for some reason.) It also adds
"Encrypted: PGP" to the headers.
I wonder if it would be better for it to encrypt the whole message, headers
and body together, then to mail that with a fresh new header that would
show nothing about the original message.
The first approach hides the contents of the message, but not its subject
or who it is from; the second hides more. Any suggestions as to which is
more useful?

I think encrypting who the message is from and the subject would be
best that way I can have a subject of "Plans to Kill Pauly Shore"
after I decrypt the message.
For how the service should work, I think you should look into MIME. You
can include encrypted text that will decrypt when you read it with
your mail program.

Well actaully, since we just recently got perl installed on our system,
I have been playing around with the elm and nn scripts. They seem to
work resonably well, but it looks like they need a little work. The do
detect if the message is PGP encrypted or if it has a PGP signature in
it and when I mail things it asks if I want to sign it or encrypt it.
They need a little polishing but they do work. Anyone else has any
experience using this? anyone got any suggestions?
Sometime when I am not so tired I am going to play with the emacs and
tin scripts.
