I am moving more to assume ms are idiots.  this seems to be the default 
config for exchange clusters.

So, we open a bugzilla and put 169.254* addresses into 'local_networks' 
by default? like rfc1918?
it the example, sa sees the internal (trusted) 172* ip, and sees 'first 
untrusted' (the 169* address!)
spf fails, rbls are consulted. all could be avoided if ms actually 
followed RFC's
