Installé sur Macbook, tous les mails redirigés sont reçu comme spam; Sur Windows 10, les mêmes mails sont reçu sans problèmes. Y-a-t-il un réglage à faire ?

This review is for a previous version of the add-on (0.9.6). 

There's probably a difference in the junk mail control settings between the Macbook and Windows 10.
Check under Tools > Account Settings > [account] > Junk Settings if all settings are the same.
Even if the settings are the same, behavior can still be different, e.g. when you have different training data for adaptive junk mail controls on the two computers or when your personal address books are different.
