Thanks for all the answers! In fact I'm quite aware of PGP/MIME and what
is correct there. I think I will use application/octet-stream as
suggested, and which many other mail clients use anyway if you attach
pre-encrypted files. The point is that I would like mail clients to be
able to detect the PGP encrypted attachments (and possibly act
accordingly), but this will usually fail if I'd use text/plain.
