It has been suggested that the IETF consider specifying an alternative
"MUST" symmetric encryption algorithm in its version of S/MIME.  One of
the alternatives is CAST. Entrust Technologies announced in January that
it was making CAST available.  From the press release:

I was at US Customs today discussing some issues regarding secure
communications between Customs and the 'Big 3'.  It was clear that it would
be hard to ge anything through over there that did not support a FIPS

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....
