Control of the spam and Open Relay Blocking System (SORBS) has officially changed hands. Security specialist GFI confirmed its acquisition of SORBS late yesterday, and also shared an idea or two about what it will do with the entity.

Other sources speculate that IF GFI re-markets/packages the service consistent with their current business model, it won't be free.

There's a few comments/observation/opinions on Slashdot: too.
