No unused E-Mail found

What does this mean "No unused E-Mail found" 
If I have 3 emails in the project and I have these settings:

And I use posting from global site list (submitted) that has removed all duplicate URLs, 
why does it come to that message "No unused E-Mail found"

You have a setting to create 10 accounts per site but then you also need at least 10 emails and not just 3 because each account needs a unique email to register.
