NAME

       dspam_clean - perform periodic maintenance of metadata

SYNOPSIS

       dspam_clean [--profile=PROFILE] [-s[signature_life]] [-p[probability_life]]
       [-u[sl,hcl,shl,ihl]] [user1 user2 ... userN]

DESCRIPTION

       dspam_clean is used to perform periodic housecleaning on DSPAM's  metadata  dictionary  by
       deleting old or useless data.

       dspam_clean  has  no effect if you use the "hash" storage driver. In that case, you should
       use the tools cssclean and csscompress (which do not currently have manual pages).

OPTIONS

        --profile=PROFILE
              Specify a storage profile from dspam.conf. The storage  profile  selected  will  be
              used for all database connectivity. See dspam.conf for more information.

       -s     Performs  stale signature purging. If a value is specified, the default value of 14
              days will be overridden. Specifying an age of 0 will delete all signatures from the
              user(s) processed.

       -p     Deletes  all  tokens  from the target user(s) database whose probability is between
              0.35 and 0.65 (fairly neutral, useless data). If a value is specified, the  default
              life  of  30 days will be overridden. It's a good idea to use this flag once with a
              life of 0 days for users after a significant amount of corpus training.

       -u     Deletes all unused tokens from a user's dataset. Four  different  life  values  are
              used:

              sl Stale tokens which have not been used for a long period of time

              hcl  Tokens with a total hit count below 5 (which will be assigned a hapaxial value
              by DSPAM)

              shl Tokens witha single spam hit

              ihl Tokens with a single innocent hit

              Ages may be overridden by specifying a format string, such as  -u30,15,10,10  where
              each  number  represents the respective life. Specifying a life of zero will delete
              all unused tokens in the category.

        user1 user2 ... userN
              Specify the username(s) to perform the selected maintenance operations  on.  If  no
              username is specified, all users are processed.

EXIT VALUE

       0      Operation was successful.
       other  Operation resulted in an error.
