You are kidding, right? 50% of this crap comes from FREEMAIL addresses, and
even more specific: 44% of this crap is delivered by aol.com.  The aol
deliveries have about 85% unique from@aol addresses, so they pretty much
'own' aol.

As most spammers try to find something other than BOTNET's at the moment, I
think it's only fair to be very critical about FREEMAIL.

Well... in itself FREEMAIL isn't spam a priori. It's just that chances are a
lot higher that it is. Hence my method of meta-ing FREEMAIL with fairly low
scoring rules, like links to free blogsites, free websites, tumblr, odd
punctuation in Subject rules, stuff like that.  Interestingly enough the
most used subject from valid freemail is "Re: " and "<none>". I don't see a
problem with being picky about freemail. The only free email provider
succesfully fighting _out_going spam is gmail.com.
