the add_headers are of great use and can be used,  the fact that they're 
not written makes it harder to catch patterns but they get hit if applied.

for example, adding :
add_header all Relays-External _RELAYSEXTERNAL_
add_header all Relays-Untrusted _RELAYSUNTRUSTED_

to local.cf triggers a bunch of rules.

many times you'll see the hits but wonder where they come from... and 
that's what we miss if MS doesn't write them.

Not a real Prio, but it would be a *very_nice_to_have*

but what's more important, relax and let the Docs do the magic on your 
body...

take care
