We need to turn on default task assignment emails to end users from Appian 7.2 s

We need to turn on default task assignment emails to end users from Appian 7.2 server.The following two properties are set to immediate in custom.properties:

server.conf.notifications.process_new_task_me_timing
server.conf.notifications.process_new_task_others_timing

The mail server setup is done on the server and end users are able to receive mails sent via Send Email smart service.Is there any other configuration required to turn on default task assignment emails?

Thanks in Advance.
