That would be a logical starting point.

It still wouldn't catch text-based steganography.  Just because a
message appears to be a discussion of the relative merits of different
baseball pitchers (or whatever) doesn't mean that it doesn't also
contain the companies master keys (or whatever).

I'm not sure even hand screening would catch the above.  You'd need to
move to the next level - have someone re-write all incoming/outgoing
mail to change the wording/phrasing etc.

I don't believe there is any technological means by which you can stop
someone smuggling information in or out of an organisation.
