Fastflux does seem to be a tool in some spammer's kits but these particular domains are probably not being used for that, at least not effectively, since they have no MX records. Are there sites that accept mail from domains without a valid MX/A record? -- Roger Marquis Roble Systems Consulting http://www.roble.com/
