Pierre, Could you look at this email client http://support.postbox-inc.com/home
It uses Thunderbird extensions
I installed IQ extension for Postbox but it did nothing.
I've got to think it's a simple tweak  but what do I know?
 
If you can make the IQ extension work in the program, that would be great. 
Thanks.
