Manage email squelching?

One of our managers would like to know if there’s a way - short of removing the relevant sections from the ticket maintenance screens - to control the use of the checkboxes that turn email notifications to particular users on and off? Alternately, are there options for searching for and reporting on tickets where a user’s notifications are squelched? (We’re currently running 3.8.10 but working towards a 4.x upgrade, so answers applicable to either version would be helpful.)

4.0.1 gives you some new improved UIs for squelching since you can
handle it globally and per-ticket.

The ShowOutgoingEmail right controls whether that box shows up.
However, it also controls whether you see in transaction history that
mail went out.
