Yes, use the right-hand side of the hashtable.
The read_hash() can read such a file (each line: sender whitespace score),
or you can construct the hash manually. But the hash belongs to
@score_sender_maps, not to %whitelist_sender (note that @score_sender_maps
is a two-level map, first level is recipient, inner level is by-sender):
@score_sender_maps = ({
# site-wide opinions about senders (the '.' matches any recipient)
'.' => [ read_hash("/var/amavis/sender_scores_sitewide") ],
});

If spam score exceeds $sa_dsn_cutoff_level, non-delivery notification
will be suppressed (i.e. sender will not receive a bounce),
despite the D_BOUNCE general setting.
Similar for $sa_quarantine_cutoff_level: quarantining is suppressed
for spam score above this cutoff level.
