As outlined here: https://community.atlassian.com/t5/Jira-Service-Desk-questions/Identifying-a-CC-in-an-email-to-incorporate-in-an-automation/qaq-p/742648
You can do a JQL search by email address and use this to pull participants (from CC) and act on the issue.
Is there a way to do this but define the rule based on an AD group (such as a project team, or otherwise defined RBAC type group)?
I'd like to create a rule to remove specific team members from participants when it's not necessary, or otherwise change the ticket based on who's being CC'd, but not have to edit each rule by full SMTP address list each time.
