of options, <parameter>BIN_DIRECTORY</parameter>,

<parameter>CONFIGURE_FILE</parameter> and

<parameter>EXIM_USER</parameter>. We also defer
|

building the <application>Exim</application> monitor program, which

requires the <application>X</application> Window System

support, by commenting out the <parameter>EXIM_MONITOR</parameter> line

in the <filename>Makefile</filename>.</para>

it. <application>Exim</application> will

accept most <application>Sendmail</application> command-line options.</para>
