6-Year-Old Says Grand Theft Auto Taught Him To Drive
If only the car was manual (I believe you refer to it as a 'stick shift' on the other side of the pond) you wouldn't have had this problem.

Corporate Email Etiquette - Dead or Alive?
Email is a tool. The job of IT is to support that tool and help people use that tool effectively. If you think employees are using IT non-optimally because of lack of training, arrange training. If employees of the company think these one line emails are the best use of the technology even after you've trained them effectively, let them get on with it.
If your problem is that your mail server can't handle all these mails, it's time to upgrade the mail server and/or switch to different software.
