<title>Installation of <application>Courier</application></title>

<para> Before you compile the program, you need to create users and groups that 
will be expected to be in place when the install script executes. Add the users 
and groups with the following commands:</para>

<screen><userinput><command>groupadd courier &amp;&amp;
useradd -c 'Courier Mail Server' -d /dev/null -g courier -s /bin/false courier</command></userinput></screen>

<para> You also need to create a bin user. If you already have a user named bin
this step can be safely ignored.</para>

<screen><userinput><command>useradd -c 'bin' -d /dev/null -g bin -u 1 bin</command></userinput></screen>

<para>This creates a
<filename class="directory">/var/run/courier</filename> directory where
all the <application>Courier</application> <acronym>MTA</acronym> pid
files will exist. This will allow <filename>courierfilter.pid</filename>
to be created. Without the <command>courierfilter</command> running the
<application>Courier</application> MTA will not work. Issue the
following commands to create
<filename class="directory">/var/run/courier</filename>:</para>

<screen><userinput><command>mkdir /var/run/courier &amp;&amp;
chown courier:courier /var/run/courier</command></userinput></screen>

<para>Install <application>courier</application> by running the following commands:</para>

<screen><userinput><command>./configure --prefix=/usr --libexecdir=/usr/lib/courier \
    --datadir=/usr/share/courier --sysconfdir=/etc/courier \
    --localstatedir=/var/lib/courier --with-piddir=/var/run/courier \
    --disable-root-check --with-mailuser=courier --with-mailgroup=courier \
    --with-paranoid-smtpext --disable-autorenamesent \
    --enable-workarounds-for-imap-client-bugs --with-db=gdbm &amp;&amp;
make &amp;&amp;
make install &amp;&amp;
make install-configure</command></userinput></screen>
