I can answer this in part... "quoted-printable" equals-escapes things such as newlines and equals signs - which of course changes the message hash, invalidating the signature. Any mailing list software which changes message encoding is EVIL. >>Its even gotten so messed up that some have their signatures show bad when >>adding a sig to the bottom of the message, leaving it off shows the >>signature as valid.
