     * iPlanet Messaging Server 5.2 (for Solaris 8 and 9) without patch
       5.2hf2.14
     * Sun Java System Messaging Server 6.0, 6.1, and 6.2 (for Solaris 8,
       9, and 10) without patch 118207-57

   To determine the version of iPlanet Messaging Server on a system, the
   following command can be run:
    % cat /etc/msgregistry.inf

   A list of instances and installs will displayed (if any) if this file
   exists.

   To determine the version of Sun Java Messaging Server on a system, the
   following command can be run:
    % /opt/SUNWmsgsr/sbin/imsimta version

3. Symptoms
