I'd like to see us change the default address-headers option value to

address_headers: from to cc sender reply-to

for the relase (the Outlook client has done that all along), and change the
Outlook client to use

experimental_ham_spam_imbalance_adjustment: False

(as everyone other than the Outlook client has done all along).

We've had several reports of the latter change helping, and no reports of it
hurting.  I'll rip out the support code after the release (in order to
minimize the chance of release breakage).

The address_headers change is long overdue; as explained before, the current

address_headers: from

default is a leftover from the days when several of us were testing with
strongly mixed-source corpora.  But these days, if, e.g., all the email that
gets sent to your myspamhoneypot at myisp.com address is spam, there's no
reason to blind the classifier to that fine To: clue.
