Scoring
.......
The BBDB can provide scoring information to Gnus in one of two ways.
1. Articles whose authors appear in the BBDB and who have
`gnus-score' fields will have their scores adjusted by the value
contained in that field.
2. Articles whose authors appear in the BBDB but who do not have
`gnus-score' fields will have their scores adjusted by
`bbdb/gnus-score-default'. If `bbdb/gnus-score-default' is `nil',
no score adjustment will be made.
The BBDB by default searches the field contained in
`bbdb/gnus-score-field' for score values. To have the BBDB use a
different field, change the value of this variable.
To enable BBDB-assisted scoring, add the `bbdb/gnus-score' function
to `gnus-score-find-score-files-function'. Assuming that you want to
preserve the default value of this variable, use a form similar to the
following:
(setq gnus-score-find-score-files-function
'(gnus-score-find-bnews bbdb/gnus-score))
Note: The default value in Gnus 5.5 is `gnus-score-find-bnews'.
Check your configuration before using the above code, as your values may
be different.
