I ran into the same/similar problem.  Diagnosis and suggested fix follow.

There is an assumption in imp/lib/MIME/Viewer/pkcs7.php that the MIME
Content-Type header is in the message body.

Both Microsoft Outlook and IMP generate an S/MIME message with the
Content-Type header in the message header.

This fix picks up the header from the mime_part object, when necessary.

Also add support for (Outlook's) application/pkcs7* content-types.

And added a couple of (missing?) requires.
