    Glenn - you nailed it... I was working on an unrelated problem that
    was also solved by turning off SELinux.&nbsp; Now both problems are
    solved.<br>
    <br>
    Now to figure out SELinux...<br>
    <br>
    Thanks!<br>

          Hi,<br>
          <br>
          I just finished an CentOS 6.2 installation followed by Postfix
          and then MailScanner. &nbsp;All seemed to be going well until I
          stopped MailScanner and then restarted it. &nbsp;For whatever
          reason, Postfix refuses to start and kicks out the following
          error:<br>
          <br>
          fatal: unable to set session and process group ID: Operation
          not permitted<br>
          <br>
          However, when I start them individually (i.e. postfix start;
          check_MailScanner) both subsystems start and mail is
          processed. &nbsp;Can anyone point me in a direction to start
          looking? &nbsp;I'm trying to wean myself off of Sendmail, so I'm
          relatively new to Postfix.<br>
          <br>
          Thank you,<br>
          <br>
          Pat<br>
