This column may be illegal. In writing it, I am inviting Philips, the Dutch electronics company, to sue me – and I’m rather hoping it will. Then I would be the first person in history taken to court for disobeying the most annoying and most pointless legal paragraph ever drafted.

The contract I’m about to break is the one that sits at the bottom of almost every business e-mail. In simple terms, it says that if the e-mail isn’t addressed to you, you must delete it at once, notify the sender and not tell a soul. I’m not the first to ignore such a command, indeed it is flouted hundreds of thousands of times every hour – almost every time that anyone forwards anything at work

The other day I received a message that was most definitely not intended for me, but was passed on by a reader who thought I might like it. It was written by Frans van Houten, the new chief executive of Philips and sent to all his 100,000 employees to tell them about a management initiative.
