Hello,
Sorry to come back to this.  Can someone verify that mailman-2.0.11-1 
was part of the RH 7.3 release and that the file 
/etc/logrotate.d/mailman contains:
/var/log/mailman/* {
    missingok
}
According to my reading of the logrotate man page, that will eventually 
kill a machine because the number of log files will exponentially explode.
Thanks,
Scott
