Why mail_forwarders_delete is rated Critical
Deletion of email forwarders is an irreversible operation that cannot be undone. Once deleted, the forwarding rule is permanently removed and would need to be manually recreated. This fits the Destructive category as it destroys existing configuration. Severity is high because misconfiguration or unintended deletion could disrupt email delivery for users relying on that forwarder, causing business impact.
From the tool's definition Tool name contains 'delete' and description states 'Delete an email forwarder' — this irreversibly removes email forwarding configuration.
