like if you send an email, you can't delete it from their inbox before they read it. Not entirely correct
I know, in a network, well I guess it is possible to do this.
At my old college this was possible... My friends went onto my account sent an email to someone, and I did not want them to see it, and so asked around, and heard it was possible...
Went to the techys there, and they said it is possible, just with the college network he said it was highly unlikley it would work. But it did... :D
@Hologide - just send another saying a) I was drunk. or b) it wasnt me
