  1. Hi, could it be, disabling this option breaks WordPress and WooCommerce from sending Mails?

    A friend of mine disabled this and he wasn’t able to receive mails from WordPress (Admin Login Mails) and also he didn’t get new order mails from his shop (WooCommerce)

    If this is the reason, would there be a way to keep this function or is this exactly what should happen if he disables this function?

    Thanks
    Rene
