See my earlier email about how "Read IP Address from Received Header" works.
That was never really answered fully but my takeaway from it is that MS
cannot determine where mail comes from if there are a variable number of
hops from your mx gateway to the MS host. Meaning, if your MX host is a
hop away, and therefore you need to set "Read IP Address from Received
Header" to 2, then you can never whitelist 127.0.0.1 because that first
Received header will not be parsed by MS.
Perhaps that's wrong but again that's just what I was able piece together
from what answers I did get to that thread.
