My current GNUS setup works fine for verifying detached signatures and
fetching the appropriate key when it's not in my keyring, but when I
get an email with an inline signature I get an `*MML2015 Result*'
buffer containing something like:

  [GNUPG:] ERRSIG F0C094A37A1E4389 17 2 00 1037992683 9
  [GNUPG:] NO_PUBKEY F0C094A37A1E4389

and a `PGP Signed Part:Failed' button in the article.  The following
are the relevant parts of my .gnus file:

  (load-library "mailcrypt")
  (autoload 'mc-install-write-mode "mailcrypt" nil t)
  (autoload 'mc-install-read-mode "mailcrypt" nil t)

  (setq mc-gpg-comment nil
        mc-pgp-keyserver-address "www.us.pgp.net"
        mc-pgp-keyserver-port 80
        mc-pgp-keyserver-url-template "/cgi-bin/pks-extract-key.pl?op=get&search=%s")

  (mc-setversion "gpg")

  (require 'gpg)
  (autoload 'gpg "gpg" t t)

  (require 'pgg)
  (setq pgg-scheme 'gpg
        pgg-default-scheme 'gpg
        pgg-default-keyserver-address "gpg.dtype.org"
        pgg-query-keyserver t)

  (setq mm-verify-option 'always
        mm-decrypt-option 'always
        gnus-buttonized-mime-types '("multipart/encrypted"
                                     "multipart/signed"))

OK, so all that's probably wrong and a complete mess, but how should I
be configuring PGG and/or Mailcrypt to handle both detached and inline
signatures?

TIA--
