Restrictions?
Where I used to work they imposed restrictions on the use of the "all" mailing list after an employee used it to express an ethical conflict with a bonus scam scheme. Naïve or not, it was relatively well formulated, but the next day that email had magically vanished from every mailbox in the company as if it never existed (except from my machine because I dumped it in print :) ). I heard later that he was marched off the premises but I wouldn't feel sorry for him - I'll get to the why later.
From that moment on, the "all" mailbox could only be used by a restricted set of people. Not that it mattered much, to entertain myself on the last day I was working there I dumped the list of all the department mailing lists and did one leaving email which copied in all those lists, in effect bypassing the restrictions on "all" just to show how pointless it was. Thanks to the "read" flag I attached I could see that I'd managed to get my email read by over 85% of the company, and that included 3 separate hits by the CEO :).
Oh, that employee? He went on to become a multi-millionaire. Well worth the exit IMHO :)
