You can mask the address with 127.0.0.1, and otherwise keep the header
as-is. Mind you, I would not expect Microsoft to pay much attention
to addresses in Received headers except when the connecting SMTP client
is "trusted" in some manner. Few users would be able to use submission
services from their broadband IP in the face of such filters.
Not all the advice you'll get on this list is sound. Generally, doing
less (be as typical as possible) is safer than doing more.
