Re: The old Reply-ALL
In a former company they blocked the Reply-All function after a member of staff emailed to all that he wasn't impressed with a proposed incentive plan. What shocked me was that the email vanished from my mailbox (being me I had a text copy of it, but it was interesting to see it happen).
The person in question was marched out of the building and went on to become a millionaire (which, given circumstances and ethics involved I found a good turn of fate).
Now for the fun bit: they may have blocked the Reply-All, but each department had a full dept mailing list. When I left, my goodbye message did indeed still go to All - after all, what good is being an evil IT specialist if you can't work your way past trivial limitations?
