On the same topic... The SpamAssassin documentation doesn't describe
this possibility, so this is why I ask the list for some clarification. 
I have a mix of private and public addresses on my network which can
send email. I have the public addresses listed in trusted_networks like
this:

trusted_networks        69.39.96.0/20
trusted_networks        12.149.230.0/24
trusted_networks        12.25.52.0/23

I'd like to add the private addresses we use too, but I'm not sure if
that would open up to more spam. If I added 10.0.0.0/8 as a trusted
network, I'm afraid it could let it spam sent from other organizations'
private networks that relay through their normal public network mail
servers or firewalls. Sort of like setting 192.168.0.0 might let in
every infected computer's email behind simple home nat boxes. Which
networks does trusted_networks apply to, as an internet path is really a 
whole bunch of networks?

TIA,
Jason
