This is also a reply to my own msg "signed MIME-PGP broken?"

As I now found out, the problem is our internal Exchange (5.x) Server
which removes for some reason all headers and signatures of clearsigned
(not signed & encrupted) PGP/MIME msgs!

Sanitizer 1.66 (Sanitizer.pm,v 1.82) does not add anything which
destroys the signature if /etc/sanitizer.cfg contains the following
lines and of course /usr/bin/sanitizer is called with parameter
/etc/sanitizer.cfg in the exim-filter configuration (which I overlooked
at first).

feat_boundaries     = 0
feat_trust_pgp      = 0

Hannes, with feat_bounderies S/MIME should also work. If not, post the
attached sanitizer.log of the invalied S/MIME msg.
