Hi, just a remark to a notice from someone, that the problem is trusting the mailing list software - that it is properly encrypting/decrypting messages, etc. Yes, this is a problem of endpoint security, but the same problem we have right now. Encryption of e-mail in mailing lists would mostly: - assure transport security from/to particular user only (remember - mailing list passwords are send to users unencrypted!) - promote use of encryption technology This are by my opinion the most important goals of this idea. BTW, if someone does not want to use encryption (because he or she has a lot of emails), there should always be an option (for public mailing lists) to decide whether he or she want to receive plaintext only, encrypted or signed mesages. (The point is in choice. :-) ) Regards, Matej
