I guess it depends where you work. I'm unfortunate enough that it's a 
99% safe bet at my place of work :-(
"training? What's training?"

I do see your point, but I'd be willing to accept the results if a user 
/did/ reconfigure their mailer to use the high port. I guess it depends 
on exactly why you need the delete-prevention.

That's why I was suggesting just moving to a high port - it's simple and 
there's no coding involved ;-) Nonetheless, it was only an idea - 
suggested in case it'd work in your environment.
