Hi,

To stop Odoo from automatically sending emails to all "To" and "CC" recipients when a new helpdesk ticket is created, you need to adjust the settings within your Helpdesk application. First, navigate to your Helpdesk Team's configuration (Helpdesk app > Configuration > Helpdesk Teams) and look for options related to "Automated customer updates" or "Email Templates" linked to ticket stages. You can either disable the automation for the "New" ticket stage or, if you still want a confirmation, edit the specific email template (found in Developer Mode under Settings > Technical > Email > Email Templates) to ensure its recipient logic only targets the original sender of the email, rather than all individuals marked in the "To" or "CC" fields who might become followers.
