Hmm, I have a bunch of stuff in ~/.muttrc , some of it thrown together,
hardly thought-out at all, and redundant, but I'll offer it for whatever
it's worth:


source /usr/share/doc/mutt/examples/gpg.rc

    color  body  brightblack   cyan    "^gpg: Signature made.*"
    color  body  brightblack   green   "^gpg: Good signature from.*"
    color  body  brightblack   yellow  "^gpg: Can't check signature.*"
    color  body  brightblack   yellow  "^gpg: WARNING: .*"
    color  body  brightwhite   red     "^gpg: BAD signature from.*"

macro   compose \CP     "Fgpg --clearsign\ny"
macro   compose \CS     "Fgpg --clearsign\ny^T^Uapplication/pgp; format=text; x-action=sign\n"



The aforementioned gpg.rc is:


# -*-muttrc-*-
#
# Command formats for gpg.
# 
# This version uses gpg-2comp from 
#   http://muppet.faveve.uni-stuttgart.de/~gero/gpg-2comp.tar.gz
#
# $Id: gpg.rc,v 1.7 2000/11/20 13:20:28 roessler Exp $
#
# %p    The empty string when no passphrase is needed,
#       the string "PGPPASSFD=0" if one is needed.
#
#       This is mostly used in conditional % sequences.
#
# %f    Most PGP commands operate on a single file or a file
#       containing a message.  %f expands to this file's name.
#
# %s    When verifying signatures, there is another temporary file
#       containing the detached signature.  %s expands to this
#       file's name.
#
# %a    In "signing" contexts, this expands to the value of the
#       configuration variable $pgp_sign_as.  You probably need to
#       use this within a conditional % sequence.
#
# %r    In many contexts, mutt passes key IDs to pgp.  %r expands to
#       a list of key IDs.

# decode application/pgp
set pgp_decode_command="gpg %?p?--passphrase-fd 0? --no-verbose --batch --output - %f"

# export a key from the public key ring
set pgp_export_command="gpg --no-verbose --export --armor %r"

# verify a key

# read in the secret key ring
set pgp_list_secring_command="gpg --no-verbose --batch --with-colons --list-secret-keys %r" 

# receive key from keyserver:
#set pgp_getkeys_command="wrap.sh -g %r"
set pgp_getkeys_command=""
