score_sender_maps wildcards

[Nick Edwards via amavis-users]

Hi,
 is '.' supposed to work in per recipients?
eg:

@score_sender_maps = ({
# a by-recipient hash lookup table, results from all matching
recipient tables are summed
# ## per-recipient personal tables  (NOTE: positive: black, negative: white)

 'someone at local.domain'  => [{'.'                 => -50.0}],
...

It seems trying to let someone at local.domain get all mail as -50, does
not work, headers do not show this at all, he is getting mail scored
at positive values.

FWIW, the global section under it (where the global parts are)
such as    '.amavis.org'                           => -30.0, etc,

 do work fine.
