You can use rate limiting to limit the number of emails that can be sent to any one email address within a specified time period. To configure this, add the a section similar to the following to the SuperADMIN local.conf configuration file. If you installed to the default directory, this file is located in C:\ProgramData\STR\SuperADMIN\server\config\local.conf.
The above example configuration means that user registration will not send more than 5 messages per hour to any given email address.
You will need to restart the SuperADMIN/SuperSERVER service to apply this change.
By default, verification links sent to users by email will be valid for 4 hours. To change this, use the following command in SuperADMIN:
<time> with the time period in minutes or hours.
