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

       -sPerforms 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.

       -pDeletes 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.

       -uDeletes 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 ... userNSpecify 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.
