Hi Steve,
This feature is in the works for our next major release, SmarterMail 17.x. The primary System Admin will be able to choose which secondary System Admins can view user passwords while impersonating. There will also be a setting available within the domain's configuration for Show Passwords to Domain Admins. Enabling this setting would allow all Domain Admins of that domain to use the Show Password functionality.
Thanks!
Andrea
