Erg, I have been meaning to do this on a per-message basis instead.
Currently, I am using the laziest means, which is PINE's latest filters
that are activated when the INBOX or another message folder is opened (bulk
processing rather than individual procmailling).

-*BRIGHT LIGHTBULB GOES ON*- :) I just got a grand idea... there's a way
in PINE emailer to pull (or [T]ake) addresses from currently received
messages and output them various ways, and of course there is a way to
import them simply into your ~/.addressbook file
I am going to write a simple sh or perl script to cull single email
addresses and output these -- one per line -- to a file such as
~/.trusted_senders or something like that. That way, the first check would
be a "test" of [ grep -i ${THE_SENDER_OR_X-SENDER_EMAIL_ADDRESS_HERE} vs
~/.trusted_senders ]. If there is a match, deliver the message.
Otherwise, a second check would be the great "is my email address even
listed in the To or CC field" test!

I was angry with (mad at?) a friend once and set up a rule that just
formailled (bounced) back to him every message he sent me... but I totally
echo your distrust of /dev/nulling messages :)
