DESCRIPTION

       dspam_maintenance  is used to remove old signatures/tokens and unimportant tokens from the
       DSPAM storage backend and purge old log entries in user and system logs.

       This script can be called from the command line or run from within cron. Either add a line
       in  your  crontab  or add this script in your cron.{hourly,daily,weekly,monthly}.  Running
       this script every hour might not be the best idea but it's your decision if you want to do
       so.

OPTIONS

       --profile=PROFILE

              Specify  a  storage  profile  from dspam.conf. The storage profile selected will be
              used for all database connectivity.

              NOTE: See dspam.conf for more information.

       --logdays=no_of_days

              All log entries older than no_of_days days will be removed.

              NOTE: Default is 31 days. (for more info: man dspam_logrotate)

       --signatures=no_of_days

              All signatures older than no_of_daysdays will be removed.

              NOTE: Default value is set by the PurgeSignatures option  in  dspam.conf,  if  this
              option  is  not set, the default value is 14 days. This option is only used for the
              Hash driver.

       --neutral=no_of_days

              Deletes all tokens from the target users database whose probability is between 0.35
              and 0.65 (fairly neutral, useless data).

              NOTE: Default value is set by the PurgeNeutral option in dspam.conf, if this option
              is not set, the default value is 90 days.

       --unused=no_of_days

              Remove stale tokens which have not been used for a long period of time.

              is not set, the default value is 90 days.

       --hapaxes=no_of_days

              Remove  tokens  with  a  total hit count below 5 (which will be assigned a hapaxial
              value by DSPAM).

              NOTE: Default value is set by the PurgeHapaxes option in dspam.conf, if this option
              is not set, the default value is 30 days.

       --hits1s=no_of_days

              Remove tokens with a single SPAM hit.

              is not set, the default value is 15 days.

       --hits1i=no_of_days

              Remove tokens with a single INNOCENT hit.

              is not set, the default value is 15 days.

       --without-sql-purge

              Do not use SQL based purging. Only run dspam_clean.

       --purgescriptdir=directory

              Space  separated list of directories where to search for SQL files used for the SQL
              based purging.

       --with-all-drivers
