Re: Securing Internet mail at the MTA level

SSH, while a quite useful tool, is not the right long-term solution for transport layer security - IP security is. It's also clear to me that for E-mail, you don't want transport level security for the system; you want "object" security, that is, digital signature and encryption of the mail message. That way, no matter how many MTAs the message passes through (and pretty much regardless of how trustworthy they are) you have end-to-end authentication, integrity and privacy.
