What version of SmarterMail are you running and what type of license are you using?
I tried version 12.5 Professional and got no custom reports for system admin or domain admin because this feature is not part of the professional license.
When I tried version 13 Enterprise I got custom reporting with scheduled email reports on all types of accounts.
