<para>To automate the running of <application>Sendmail</application> at

init script included in the 
<xref linkend="intro-important-bootscripts"/> package.</para>

<note><para>The -qNm option to <command>sendmail</command>, where N is number 
of minutes, controls how often Sendmail will process the mail queue. A default 
of 5 minutes is used in the init script. Individual workstation users may want 
to set this as low as 1 minute, large installations handling more mail may
want to set it higher.</para></note>
