"Safe and Secure" is a misnomer with Unix mail under any flavor.
Mail is transmitted in cleartext across the internet. How much
privacy do you think there is _anywhere_ in the process?
The original problem was to handle the permissions problems on the
mail spool directory. I believe the thread has lost sight of that,
and become directed at redesigning the mail process, which is
well beyond the scope of this thread.
