    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 (,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.
