Well, that's the problem, isn't it?  If your expectations for e-mail are 
shaped by experience with paper mail and you don't realize how different 
an organization's internal highly controlled mail system is from e-mail on 
the outside, you're inevitably going to be surprised, sometimes 
unpleasantly.

I would like for us to avoid the Yes Minister Tautology: We must do 
something, this is something, therefore we must do this.
