After reviewing this, I think we have no choice but to lookup all the

Sender can be use to change the lookup order.
Which does not give you any benefit that I can see. More useful would
always be to lookup the Sender in SSP just as if it had been in the From
header.
Examples:
#1: sender matching domain
From: p1 @ a.com, p2 @ b.com, p3 @ b.com, p1 @ c.com
Sender: p4 @ b.com
In that case, you have already looked up b.com in the From, so no need to
do it again, of course.
#2: sender no matching domain
From: p1 @ a.com, p2 @ b.com, p3 @ b.com, p1 @ c.com
Sender: p4 @ d.com
That might be where p4(_at_)b(_dot_)com was a mailing list expander. If the mailing
list published an SSP and signed, then that would get checked (though I
doubt mailing lists would often be specifying "strict").
If any of [abc].com was 'strict', then the message would get through iff
the mailing list had not broken their sig(s). If they were all 'all', then
it would get through if either their sig worked or the mailing list's sig
worked.
#3: no sender
From: p1 @ a.com, p2 @ b.com, p3 @ b.com, p1 @ c.com
No problem in that case.
