<h1 id="mutt">Mutt</h1>
<p>Mutt is a powerfull mail reader,
<a href="http://www.mutt.org/doc/devel/manual.html">Mutt Manual</a>,
is the best place to find information.
I recomend <a href="http://realprogrammers.com/jump_start/mutt/">Jump Start: Mutt</a>,
name says it all.</p>
<h2 id="install">1. Install</h2>
<p>Sysdoc <a href="../ports/mutt">mutt port</a> is a copy
of opt mutt port with built in SMTP and SASL. Alternative
is to use external programs like msmtp.</p>
<pre>
$ prt-get depinst mutt cyrus-sasl
</pre>
<p>Verify if mutt have SMTP support;</p>
<pre>
$ mutt -v | grep USE_SMTP
+USE_POP +USE_IMAP +USE_SMTP
</pre>
<p>Verify if mutt have SASL support;</p>
<pre>
$ mutt -v | grep USE_SASL
+USE_SSL_OPENSSL -USE_SSL_GNUTLS +USE_SASL -USE_GSS +HAVE_GETADDRINFO
</pre>
<p>Mutt will recognize follow locations for configurations
files;</p>
<dl>
<dt>/usr/etc/Muttrc</dt>
<dd>System configuration file for mutt.</dd>
<dt>~/.muttrc</dt>
<dd>User configuration file on home root.</dd>
<dt>~/.mutt/muttrc</dt>
<dd>User configuration inside home mutt folder.</dd>
</dl>
<p>Skeleton configuration will use the second user configuration
(inside home mutt folder);</p>
<pre>
$ sudo mkdir /etc/skel/.mutt
$ sudo touch /etc/skel/.mutt/mail_alias
</pre>
<p>Get gpg.rc example from distribution file;</p>
<pre>
$ tar xf /srv/ports/distfiles/mutt-1.6.1.tar.gz mutt-1.6.1/contrib/gpg.rc
$ sudo mv mutt-1.6.1/contrib/gpg.rc /etc/skel/.mutt/
</pre>
<p>If you like to use sample.muttrc distributed with
source code;</p>
<pre>
$ tar -xf /srv/ports/distfiles/mutt-1.6.1.tar.gz mutt-1.6.1/contrib/sample.muttrc

<p>Justin R. Miller <a href="http://codesorcery.net/old/mutt/mutt-gnupg-howto">Mutt Gnupg Howto</a>
"Everything You Need To Know To Start Using GnuPG with Mutt"
is a great reference. Multiple email accounts are gracefully
handle by folder hooks, this hooks are defined in muttrc.
When we change folder the hook is called, setting up the email
account sepecific settings.<p>
<p>Lets start configuring the two accounts, one for host system
email and another for external email account. Change pgp_sign_as according to your specific sub key for signing. Change
<a href="conf/etc/skel/.mutt/muttrc">muttrc</a> with your
preferences;</p>
