No. RFC-3156 (PGP/MIME) does not really care about this mime type
OpenPGP signed messages are denoted by the "multipart/signed" content
type, described in , with a "protocol" parameter which MUST have a
value of "application/pgp-signature" (MUST be quoted).
... the mulitpart/signed container has two parts: An arbittrary MIME
part and a MIME part with a content-type as described by the "protocol"
paramter (e.g. application/pgp-signature). Any other use is not defined
> In that case, is there a MIME type that has been defined for clear text
application/pgp-signature is often used. However, if you already change
to MIME type to an application/foo type, the verifying MUA needs to be
abale to cope with that. It would thus be easier to use PGP/MIME
Clearsigned is a hack from the dark ages of the mid-90ies where most
MUAs were not MIME aware.
