Ubuntu Manpage: dspam_clean - perform periodic maintenance of metadata

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.
