Currently, if you have an automation setup to send an email to a user that is "Not Active/Removed/Deleted/Suspended" on just the Jira site the email will still be sent. This can cause a potential security risk. 

The automation smart value  {{reporter.active}} doesn't check the Jira instance to see if a user is active or inactive so that doesn't solve the issue for Jira Automation sending an email to a user that is not on in the Jira instance but if that user's account is Active in Jira. 

EX: Would be nice for the automation smartvalue be able to see if the user is active in the Jira instance or some other indicator to toggle that would remove the ability for the Automation rule to send an email to a user who is not Active in the Jira instance that triggered the email. 

Related: Email notifications are sent to inactive users who own rules that have failed.
