====== Client mail Mutt ======

Mutt est un client mail en mode texte qui peut s'avérer pourtant très puissant. Beaucoup de client mail en mode graphique sont lourds et offrent des fonctionnalités pas toujours nécessaires (calendrier, etc...). Mutt se contente de pouvoir recevoir et envoyer des mails. Pour l'installer sur [[http://www.debian.org|Debian]], on installe une version patchée ainsi que w3m pour avoir un rendu des mails HTML.
<code bash>aptitude install mutt mutt-patched w3m</code>

La configuration de Mutt se fait via le fichier //~/.muttrc// on peut aussi poser des extras de configuration dans le répertoire //~/.mutt//. La configuration ci-dessous détaille la manière d'utiliser Mutt avec Gmail.

Fichier .muttrc :

Si l'on utilise une clé GPG pour chiffrer ou déchiffrer des mails, on met dans le fichier //~/.mutt/crypto// le contenu suivant :
<code>
set pgp_decode_command="gpg %?p?--passphrase-fd 0? --no-verbose --batch --output - %f"
set pgp_verify_command="gpg --no-verbose --batch --output - --verify %s %f"

set pgp_clearsign_command="gpg --no-verbose --batch --output - --passphrase-fd 0 --armor --textmode --clearsign %?a?-u %a? %f"
set pgp_encrypt_only_command="/usr/lib/mutt/pgpewrap gpg --batch --quiet --no-verbose --output - --encrypt --textmode --armor --always-trust -- -r %r -- %f"
set pgp_encrypt_sign_command="/usr/lib/mutt/pgpewrap gpg --passphrase-fd 0 --batch --quiet --no-verbose --textmode --output - --encrypt --sign %?a?-u %a? --armor --always-trust -- -r %r -- %f"

set pgp_timeout=60

# it's a regexp used against the GPG output: if it matches some line of the output
# then mutt considers the message a good signed one (ignoring the GPG exit code)
set pgp_good_sign="^gpg: Good signature from"

# mutt uses by default PGP/GPG to sign/encrypt messages
# if you want to use S-mime instead set the smime_is_default variable to yes

Certaines personnes (beaucoup ?) envoient des mails au format HTML. Mutt étant un client en mode texte, il faut passer par w3m (navigateur web en mode texte) pour faire le rendu des mails HTML. Pour cela, il faut créer un fichier //~/.mailcap// et y mettre ceci :
<code>
text/html;      w3m -I %{charset} -dump %s; nametemplate=%s.html; copiousoutput
</code>

Enfin pour rajouter automatiquement une signature à la fin des mails, il faut simplement mettre le contenu de la signature dans le fichier //~/.mutt/signature-gmail//.
