man dspam_clean (Commandes) - perform periodic maintenance of metadata
NAME
dspam_clean - perform periodic maintenance of metadata
SYNOPSIS
dspam_clean [c -s[signature_life]c ] [c -p[probability_life]c ] [c -u[sl,hcl,shl,ihl] ] [c user1 user2 ... userN ]
DESCRIPTION
dspam_clean is used to perform periodic housecleaning on DSPAM's metadata dictionary by deleting old or useless data.
OPTIONS
- -sc
- 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.
- -pc
- 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.
- -uc
- 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 ... userNc
- 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.
