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.
