      Some important features provided by 8.8.6 includes a new group
      of rulesets to avoid mail "spamming" (i.e., sending of unsolicited
      mail to large number of users) and to prevent mail "spammers"
      from using your host as a mail relay point.

      Sendmail 8.8.6 provides four new named rulesets which can be used
      to check and reject abusive mail messages.

      patch hub for HP-UX 10.20, 10.30, and 11.0.  An upgrade is
      available for HP-UX 10.00, 10.01, and 10.10.  Hewlett-Packard
      recommends installing sendmail 8.8.6 for HP-UX 10.00, 10.01,
      and 10.10 as an optional version upgrade.  This upgrade is
      not available from the Electronic Support Center (ESC) patch
      hub, but from:

    http://www.software.hp.com/software/HPsoftware/Sendmail/index.html

      There are numerous new configuration options available and various
      issues involved in upgrading to Sendmail 8.8.6.  The URL above
      provides additional information regarding the impact of the
      upgrade.
