Trusted Solaris User's Guide

Enforcing MAC for Email Transactions

The Trusted Solaris environment enforces mandatory access control whenever you use email. When you send email, the Trusted Solaris environment prevents users with insufficiently high clearance from receiving it. On the receiving end, email is sorted by the labels within your account range. Your current label must be at the same level as the email message you intend to read; otherwise you must change your current label.
