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= 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.
