DESCRIPTION

15       dspam_clean is used to perform periodic housecleaning on DSPAM's  meta‐
16       data dictionary by deleting old or useless data.

OPTIONS

20        --profile=PROFILE
21              Specify  a  storage profile from dspam.conf. The storage profile
22              selected  will  be  used  for  all  database  connectivity.  See
23              dspam.conf for more information.
24
25
26       -s     Performs  stale  signature purging. If a value is specified, the
27              default value of 14 days will be overridden. Specifying  an  age
28              of 0 will delete all signatures from the user(s) processed.
29
30
31       -p     Deletes all tokens from the target user(s) database whose proba‐
32              bility is between 0.35 and 0.65 (fairly neutral, useless  data).
33              If  a  value  is  specified, the default life of 30 days will be
34              overridden. It's a good idea to use this flag once with  a  life
35              of  0 days for users after a significant amount of corpus train‐
36              ing.
37
38
39       -u     Deletes all unused tokens from a user's dataset. Four  different
40              life values are used:
41
42              sl  Stale  tokens  which have not been used for a long period of
43              time
44
45              hcl Tokens with a  total  hit  count  below  5  (which  will  be
46              assigned a hapaxial value by DSPAM)
47
48              shl Tokens witha single spam hit
49
50              ihl Tokens with a single innocent hit
51
52              Ages  may  be  overridden by specifying a format string, such as
53              -u30,15,10,10 where each number represents the respective  life.
54              Specifying  a  life of zero will delete all unused tokens in the
55              category.
56
57
58        user1 user2 ... userN
59              Specify the username(s)  to  perform  the  selected  maintenance
60              operations  on.  If no username is specified, all users are pro‐
61              cessed.
