Suggestion to improve things.

Really, this bug occurs mostly because there are two algorithms for inferring
trust when private/reserved IPs exist.

1) Trust all reserved IPs, plus first non-reserved. 

2) Trust all reserved IPs, first non-reserved untrusted.


Algorithm 1) works if your outer-most MX has a non-reserved IP, and fails with
over-trust if your outer-most MX is using some kind of static-mapped NAT or
other mechanism that gives it a reserved IP.

Algorithm 2) works if you have a NATed MX, but fails with under-trust if your MX
is not NATed.

Why not add a config option that will control if SA assumes the MX is NATed or
not?  

i.e. trusted_networks_nated_mx  (default disabled)

This would at least make it easy for people to fix, and obvious in the manpage
they might want to consider it.
