Trusted Solaris 8 4/01 software checks host and user labels before sending or forwarding mail.
The software checks that the mail is within the accreditation range of that host, as described in the following list and in Chapter 8, Specifying Routing and Security for Remote Computers.
The software checks that the mail is between the account's clearance and minimum label.
