I view link encryption for SMTP -- i.e. SMTP over TLS -- as having two functions.
1) It frustrates "vacuum cleaner" mail tapping efforts to some degree. 2) It can be used effectively for authenticating the posting of a mail message from an MUA to the first hop MTA. I don't see it as being useful for making sure your mail is actually "secure", but I think it is a valuable thing to turn on as much as one can, if only to reduce "casual eavesdropping". It certainly can't stop (for the most part) concerted attacks, but I don't think most people view it as being useful for that. -- Perry E.
