In my original message, I was asking about S/MIME signed messages. S/MIME encrypted messages is a separate matter: your message body is never transmitted in plain text, nor is quoted-printable encoding used.
The "smime.p7m" MIME part is actually a base64-encoded binary file which represents the encrypted message body. Regards, Andrey.
