To answer your question in the way email is currently use you can not
be certain because:
1. Sender headers could be added by mail list for Resent- message
and you would not be able to tell which one was first
That's what I said.
2. Headers sometimes get rearranged, even Resent-* headers
Do they really? I have never seen this. Under what circumstances do
Resent-* headers get changed such that they'd change the answer we get
for the 'most recent sender', at an intermediate site? To what extent to
we need to care?
Unless I can actually reject mail for the crime of lacking a MASS
signature when it should have one, MASS is entirely useless to me.
