Mailman RPM does not properly handle package installation and upgrade.

The mailman package for Red Hat Linux 9 does not properly handle package
installations and upgrades.

Mailman is a mailing list manager.

The mailman-2.1.1-2 package shipped in Red Hat Linux 9 has an RPM
installation bug that leaves a critical configuration parameter
uninitialized, preventing the package from properly running after
installation. On upgrade the package also fails to preserve the user's
previous configuration file, resulting in data loss.

Users of mailman-2.1.1-2 should upgrade to the updated package, which is
not susceptible to this issue.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
