I have received the following message: "Data protection - computer users. When we send email messages we often copy the message to another person. A warning has been issued that we risk being reported to the Information Commissioner as we could be breaking the terms of the Data Protection Act. Under this legislation, it is forbidden to publish and share other people?s email addresses unless they have given permission.
The answer is to use the "blind copy" facility which is in all email programmes."
I'm not convinced about this. If we send official snail mail, and copy it, then all recipients can see the copy addressees - and all data (not just e-data) is now covered by the data protection act. However, whenever I broadcast the odd e-joke, or forward mail which I have received, I do make a point of removing all addresses on the original, and sending the material on as bcc.
