Am seeing some spam where the sender's From_ address's domain
doesn't have an MX record.  Was considering noting that fact
in the header as an extra X- field, and then letting SA score
it negatively. Has anyone tried that sort of thing?  Can
you offer some prototype code that does something like that?
