Well, a quick glance at Mail/SpamAssassin/Bayes.pm doesn't list the
From: header in $IGNORED_HDRS but indeed performs some actions on this
header. Dunno for sure, though.

Anyway, this will have a minor effect only, as the bulk of the source
for Bayes is gathered from the mail body. And Bayes doesn't kick in,
until it is trained sufficiently -- which seems to be a reason for the
OP.


On a related note, Auto-Whitelisting acts on the From: header, judging
from previously received mails and adjusting the score. Thus training
(marking as non-Junk) these mails is very important.
