I like the concept, but not with the ad for commercial PGP at the
expense of GnuPG and others. Though I think the following poster who
suggested scanning the email itself for the PGP identifier might be more
useful and less prone to being fooled by someone who just puts the
header in there without actually encrypting. Also, headers don't have to
be in a specific order, it's possible that "From:" or "Subject:"
accidentally get moved ahead of "X-PGP-Encrypted:" by mistake and that
would result in a false bounce.
