Carlo Catajan, Yahoo Mail product manager, says the company ended its relationship with Goodmail Systems in February. Yahoo felt its control of its infrastructure gives it more control and visibility of what users want and it can offer the same functionality in-house.

Dan Lewis of Microsoft's Hotmail said it is still in discussions with Goodmail about how to use it in some areas.

Goodmail has a CertifiedEmail product, among other platforms.
