As I recall, DES was SHOULD.  From what I learned today, I'd say that DES
is MUST.  And when AES is done then, well I'm not so sure of that....

If DES is a MUST then US software companies will have a difficult time
exporting S/MIME-compliant products.



Presumably DES-40 should be no more difficult to export than RC2-40
(Lotus does it), and DES-56 should be much easier to export than RC2-128.
