Batching email notifications is disabled in Data Center 10.3 and I can find how to re-enable it

[Alastair Munro]

Docs advise you can find it under Mail, but there is no option. Also displaying System Info it shows:

Jira inform - batchers - 4.1.5 Disabled

Jira inform - batching plugin - 4.1.5 Disabled

Reason I want to enable it is Jira Troubleshoot and Support plugin fails to enable as the batching plugin is not available:

To re-enable the plugin (mysql). The restart jira. After restarting Jira you will have a Troubleshooting and Support section in System (plugin is enabled). Now you can choose whether to batch up emails or not. Looks like someone disabled the plugin many years ago to disable batching of emails, but the plugin now allows you to set it without disabling the plugins.
