This is great. I am glad K9 will live on. I didn't think it wouldn't anyway because frankly K9 is established software and Thunderbird doesn't seem to have anything in that space. It wouldn't make sense to kill it and redo it. This is not Microsoft after all, which would take the product and cripple it so much that it has one third the features and the Microsoft name.

However this particular deal sounds a lot like white labeling, don't you think ? :)
