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.
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.
