我已經使用 mutt 一段時間了，雖然我可以（並且確實）簽署了我的所有電子郵件，但我無法加密任何電子郵件。我從網路上的某個隨機位置獲取命令。這是我目前的設定。我已經重新排序和格式化了一些東西，以便它們至少在某種程度上對齊。
set pgp_sign_command ="gpg --no-verbose --batch --output - --passphrase-fd 0 --armor --detach-sign --textmode %?a?-u %a? %f"
set pgp_encrypt_only_command="gpg --no-verbose --batch --output - --quiet --armor --textmode --always-trust --encrypt-to %a -r %r --encrypt %f"
set pgp_encrypt_sign_command="gpg --no-verbose --batch --output - --passphrase-fd 0 --armor --textmode --encrypt --sign %?a?-u %a? --always-trust --encrypt-to %a -r %r -- %f"
當嘗試加密訊息時，我收到此錯誤：
usage: gpg [options] [filename]
當嘗試簽名和加密時，我收到此錯誤：
usage: gpg [options] --sign --encrypt [filename]

最好的選擇是使用 GPGME 庫:
set crypt_use_gpgme
但如果你想要舊的命令方法，mutt 本身帶有/etc/Muttrc.gpg.dist包含範例命令（此處包含整個文件）：
# -*-muttrc-*-
#
# Command formats for gpg.
#
# This version uses gpg-2comp from
# http://70t.de/download/gpg-2comp.tar.gz
#
# $Id$
#
# %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.
# Note that we explicitly set the comment armor header since GnuPG, when used
# in some localiaztion environments, generates 8bit data in that header, thereby
# breaking PGP/MIME.
