dspam_clean(1)
NAME
dspam_clean - perform periodic maintenance of metadata
SYNOPSIS
dspam_clean [-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.
OPTIONS
- -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 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.
