- A breech of security is when someone can gain unauthorized access to
- your host; the sendmail debug verb that the Morris worm took advantage
- of was a security hole. A breech of authentication is what forgery
- permits, in which you cannot know who sent you a message. As has been
- pointed out repeatedly, this is also a problem with paper letters. As
- has also been pointed out, PEM and similar systems are the proper way
- to address this problem.

-
- Privacy is a third issue entirely, different from host security and
- authentication. To assure privacy, no method will work other than
- cryptography, period. The internet is not and cannot be secure in its
- transmitions; with hundreds of thousands of miles of line, its
- impossible to keep people from tapping some of it. This is NOT an SMTP
- failing.
