Quick comment - the OP specifically asked for something "to force lower
score on exact From: address."

whitelist_from is a last resort as it is subject to spoofing by forged
addresses.

This topic reminds me of my occasional desire to be able to supply
individual score points (optional, overriding a default) with each
whitelist_from* and whitelist_from_dkim entry, taking into account
reputation of each sender, e.g.:
whitelist_from_dkim *@intl.paypal.com paypal.com -10
whitelist_from_dkim *@amis.net amis.net -20
whitelist_from_dkim *@yahoo.com yahoo.com -4.0
whitelist_from_dkim *@yahoo.sg yahoo.sg -2.5
whitelist_from_dkim *@gmail.com gmail.com -5
Would such a concept interfere with a custom of supplying
score points in a 'score' directive only? Any alternative
syntax approaches?
In a long run, some more-general 'reputatation' mechanism
may need to be invented.

Specifically, whitelist_from_rcvd. Don't be seduced by whitelist_from.
See the list archives for why.
