Curt,

Please tell me that your kidding about your comment:

"An alternative is to allow only a proprietary extension
through, like .inc  Legitimate senders would rename 
the file, be it .exe .doc .jpg, indicate in the body 
of the message what the true extension is,
and the receiver merely renames it."

If your not kidding it furthers the arguement that 
all those certification characters at the end of 
your name are worthless.  

"Having NO security is better then, security by obscurity !!

I would have hoped you were taught atleast that before begin
handed a CISSP certification and you should disclose this view
you have to your employeer so they understand who is protecting
them.

Very draconian in todays world, and not productive by the way
some folks
do the work they have to do with limited capabilities these days.
It
seems that we might was well revert back to only allowing
e-mail in plain text

Ah, I wish...  An alternative is to allow only a proprietary extension
through, like .inc  Legitimate senders would rename the file, be
it .exe
.doc .jpg, indicate in the body of the message what the true extension
is,
and the receiver merely renames it.  A little trouble yes, but it
virtually
eliminates email propagated viruses from the corporation.
