- Possible? Of course. So what ?
-
- Before I get technical, allow me some general comments:
- It is technically always possible to monitor electronic mail, unless you use
- powerful encryption techniques. I also can read my user's mail, and I
- occasionally have to do so (or what would you do with a volume running
- out of space because of unread mail from several mailing lists, e.g.).
- But, trust me, it is possible to read user's mail without leaving
- any signs of your activities.
- All users should be aware of the fact, that
- - electronic mail can technically read by everyone involved in the process
- of transmitting it, and
- - system adminitrators might read it if necessary to keep the system
- running, but not else.
- So in the end, you have to trust the people who run your system - or you
- can't trust the system, too. Spreading wild rumours like the one above
- likely offends your system folks. I personally would get VERY angry if I
- heard one of my users ran around telling everyone I would read their mail
- on a regular basis.
- So go to your LAN adminitrator/supervisor/whatever and politely ask
- him. In the end it is his job to keep the system running so that you
- can use it to earn the money he is paid with.
-
- Regarding the technical point, these "Mail"-directories in a novell
- system are the only definitely existing user-related directories.
- A lot of programs use them to store their setup or configuration
- files or marks. Since this file is updated during login, it is most
- probably used by a program run from the login script.
- If you want to know for sure, check the system login-script.
- It is a public readable text-file SYS:PUBLIC\NET$LOG.DAT . All commands
- therein are explained in the Novell online-help database.
-
- So, as a summary, it is possible, but not very likely, that your
- system adminitrator reads your mail. I would not bet on it.
