But that's partly because even the definition describes the point: _Simple_ Mail Transfer Protocol. If you think of the situation in the 80's when X.400 was planned and there were no standard way of transferring messages between different vendor systems. It was at least an effort to create a standard. I know it's not the best one, but probably more thoroughly planned than SMTP. Kari
