After moving some messages into the folder, FairEmail will start to move messages automatically into this folder.

Classification should be considered as a best guess - it might be a wrong guess, or the classifier might not be confident enough to make any guess.

To prevent the email server from moving a message into the spam folder again and again,
auto classification out of the spam folder will not be done.
The message classifier calculates the chance a message belongs in a folder (class).
There are two options in the miscellaneous settings that control if a message will be automatically moved into a folder,
provided that auto classification is enabled for the folder:
* *Minimum class chance*: the minimum chance a message belongs in a folder (default 20 %)
* *Minimum class difference*: the minimum difference with the next best folder (default 50 %)
Considering the defaults option values:
* Apples 40 % and bananas 30 % would be disregarded because the difference of 25 % is below the minimum of 50 %
* Apples 15 % and bananas 5 % would be disregarded because the chance for apples is below the minimum of 20 %
* Apples 50 % and bananas 20 % would result in selecting apples
Classification is optimized to use as little resources as possible, but will inevitably use some extra battery power.
You can delete all classification data by turning classification three times off.
