Use this option to purge the mailing list of old information. It is not required that this option be used and often many users never purge their mailing list file. At most you would run this option once a year, but it can be run as often or as little as desired. This option will delete all entries from the mailing list file that match your prompt responses. Please be careful that your purge specifications are correct before continuing with this option. You can only recover your mailing list entries by restoring a backup copy.
