I agree with you on this but I don't use filetype.conf because for now
there are no viruses that ask people to rename _exe inti .exe. I also
tell people to rename their .exe into something else if they want them
to pass through my servers.
As soon as one virus goes that route I will have to activate
filetype.conf but I predict my users won't like it... But implementing
security measures has always been PITA for users.
