<title>Installation of <application>Exim</application></title>

<para>Before building <application>Exim</application>, you should 
create the group and user exim which will run the exim daemon:</para>

<screen><userinput><command>groupadd exim &amp;&amp;
useradd -d /dev/null -c "Exim Daemon" -g exim -s /bin/false exim</command></userinput></screen>

<para>Install <application>Exim</application> with the following 
commands:</para>

<screen><userinput><command>sed -e 's,^BIN_DIR.*$,BIN_DIRECTORY=/usr/sbin,' src/EDITME | \
  sed -e 's,^CONF.*$,CONFIGURE_FILE=/etc/exim.conf,' | \
  sed -e 's,^EXIM_USER.*$,EXIM_USER=exim,' | \
  sed -e 's,^EXIM_MONITOR,#EXIM_MONITOR,' > Local/Makefile &amp;&amp;
make &amp;&amp;
make install &amp;&amp;
cp doc/exim.8 /usr/share/man/man8 &amp;&amp;
ln -s exim-4.24-1 /usr/sbin/exim &amp;&amp;
ln -s exim /usr/sbin/sendmail</command></userinput></screen>

</sect2>

<sect2>
<title>Command explanations</title>

<para><command>sed -e ... > Local/Makefile</command>: Many of 
<application>Exim</application>'s configuration options are compiled in. 
This command specifies the minimum set of options, 
<parameter>BIN_DIRECTORY</parameter>, <parameter>CONFIGURE_FILE</parameter> 
and <parameter>EXIM_USER</parameter>. Additionally, building the 
<application>Exim</application> monitor program is deferred, as it 
requires <application>X</application> Window System support, by commenting 
out the <parameter>EXIM_MONITOR</parameter> line in the 
<filename>Makefile</filename>.</para>

<para><command>ln -s exim /usr/sbin/sendmail</command>:
Creates a link to <command>sendmail</command> for applications which need 
it. <application>Exim</application> will
accept most <application>Sendmail</application> command-line options.</para>

<title>Configuring Exim</title>

<sect3><title>Config files</title>

<para><filename>/etc/exim.conf</filename> and 
<filename>/etc/aliases</filename></para>

</sect3>

<sect3><title>Configuration Information</title>

<para>Create the Exim configuration files with the following commands:</para>

<screen><userinput><command>cat &gt;&gt; /etc/aliases &lt;&lt; "EOF"</command>
postmaster: root
MAILER-DAEMON: root
<command>EOF
exim -v -bi &amp;&amp;
/usr/sbin/exim -bd -q1m</command></userinput></screen>

<note><para>To protect an existing <filename>/etc/aliases</filename> file, 
append these aliases to it if it exists. This file should be checked and 
duplicate aliases removed, if present.</para></note>

<para>To automate the running of <command>exim</command> at startup, install 
the <filename>/etc/rc.d/init.d/exim</filename> init script included in the 
<xref linkend="intro-important-bootscripts"/> package.</para>

<screen><userinput><command>make install-exim</command></userinput></screen>
