I'm not asking for the list to encrypt the e-mails to each member, but just to pass along the esig as it does now... see this esig mail. May be the list can check the esig of the person posting, or each one of us check it.. I would prefer if the list does it and held anything else for individual approval by moderators of the list--On Sunday, 08 February, 2004 20:21 -0600 Spencer Dawkins <spencer@xxxxxxxxxxxxx> wrote: > Hi, Ed, > > I don't know everything about e-mail, although I do send and > receive e-mail from time to time. > > I would be interested in reading reasons from others why this > is a bad idea. It seems interesting to me. Let's assume I have a mailing list. Take the IETF list as a handy example. This technique implies that (i) The IETF list exploder needs to track several thousand (I'm just guessing at the number here) public keys, encrypt each list message separately and mail it separately or encrypt each message going out for all of the recipients (the latter is somewhat less network intensive on some dimensions, and slightly less computationally intensive, but not much, and would ensure that every message going out, even trivial ones, was 40K-50Kb long, minimum). With current computational capacity at the secretariat, I think that would probably throttle the IETF list back to a handful of messages a day, total. That might be a good idea, but is probably not the intent :-(
If he subscribes himself, then we have his e-mail address and then his provider and may be an IP and time, so we could track him down in the real world and may be sue him...(ii) All a spammer would need to do would be to guess or know one of the addresses that is subscribed to the IETF list, or subscribe temporarily himself, then post the spam to the list, in order to get the list exploder to do that work for him.
Now, Franck's suggestion would work better from a list
