Good afternoon, we have a problem with spam in JSM. We receive a lot of email requests from the same domain, but with different emails, for example test1@rest.com, test2@rest.com, test3@rest.com, test4@rest.com. How do we limit the creation of tickets from 1 domain for a certain period of time? For example to start from a domain test.com couldn't create more than 5 tickets per hour?
