Risk Management Platform Ideas

We have a client that has the "Disable all task assignment emails and communications" checked on the Communication Settings page. If there is an assignment assigned and the check box to send the emails immediately is checked, the email still send. And to go a step further this client also has "Do not send email to supervisor if employee has no email address" the emails are sent to the supervisor, manager or Site admin. The follow up emails appear not to be sent. I believe that the original email should not be sent if the disable all checkbox is checked and the supervisor should not receive emails either.
