I think a very high percentage of the pinksheet pump and dump spams and the viagr*, enl*rgment, etc spams have fake addresses in the From headers

So how about publishing some SPF data on your domain so those so inclined can use it toward reducing the ungodly amounts of backscatter you guys must get (and which causes you to tarpit other carriers and forwarders)

Same goes for comcast.

Even a softfail ~all will help out buckets.

It's all but eliminated the backscatter we send to hotmail. If they can do it....
