NAME
       dspam_clean - perform periodic maintenance of metadata

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

DESCRIPTION
       dspam_clean is used to perform periodic housecleaning on	DSPAM's	 meta-
       data 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 stor-
       age profile selected will be used
	      for all database connectivity. See dspam.conf for	more  informa-
	      tion.

       -sPerforms  stale  signature  purging. If a value is specified, the de-
       fault 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 as-
	      signed 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.
