Modifying the Subject: line is a Bad Thing; it invalidates digital signatures.
Which digital signatures are you talking about? Neither S/MIME nor OpenPGP sign the headers in messages, only the bodies.
S/MIME can sign the Subject: header (see RFC-1848, section 6.3)
RFC 1848 is for MOSS, not S/MIME or OpenPGP. MOSS had no significant implementation.
