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=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 proba‐
bility 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 train‐
ing.
-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 pro‐
cessed.
EXIT VALUE
0 Operation was successful.
other Operation resulted in an error.
