I have noticed this is case-sensitive. If i create a folder "test" but someone sends the email to "user+Test at example.com" it wont get sorted into the folder. And other way around, if i make a "Test" folder then emails with capitalized Test make it there but non capitalized addresses get sent to the inbox.

Is there anyway it make this feature case-insensitive?
