There are good reasons to prefer a PGP/MIME and S/MIME signature
standards over inline PGP. These standards have been around for a long
time, and modern mail user agents should be able to cope by now, even if
all they do is discard the multipart/signed wrapper and trailing
It would be really useful to hear about specific MUAs that can't handle
PGP/MIME-signed messages like this one, and to get clear descriptions of
the failure modes.
But without these kind of specific reports, vague statements like "most
of those will have difficulty" just sound like FUD to me.
