Very draconian in todays world, and not productive by the way
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.
