I just ran a test with the reply by email feature and within on hour disaster struck: one user had used the feature and his email included a signature which did not start with ‘–’. It included his private phone number. It was removed before any damage was done, but this did get me thinking: many users don’t care about the ‘–’ convention, and as a result all kinds of info might be shared without them being aware. Did anyone run into a similar situation? What’s a ‘best practice’ here?
