Aside from the invalid mails, this article suggests they're mostly identifying spam by the source IP (ie. their customer's IP) being listed in a DNSBL. So how come they need this super-duper real-time content scanning infrastructure ? Why wouldn't they download the DNSBLs, and simply run an offline grep for entries in their own IP space ?
I understood from the article that they were just describing an early prototype and that they were planning to add content scanning checks later - see the "other spam detection techniques" section.
