Your inbox namespace seems to be ok and is also defined in your doveconf 
-n output.

Somehow there seems to be an empty namespace in addition to your inbox 
namespace.

Is there a second namespace in your config somewhere?

Just guessing:
Could it be with Thunderbird that the second namespace is ignored when 
there is no subscription to it and the Apple mailprogram behaves 
differently?
