Delete a mailbox (frees the slot — mail is destroyed).
AI agents call gandi_email_delete_mailbox to permanently remove resources in Gandi — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes mailbox data. Email deletion is not reversible and represents permanent data loss. While the blast radius is somewhat limited to a single mailbox rather than an entire system, the destructive nature and unrecoverable data loss justify the 'Destructive' category and 'high' severity. Confidence is high because the description explicitly states mail is destroyed.
From the tool's definition "Delete a mailbox (frees the slot — mail is destroyed)." The tool permanently destroys email data and cannot be undone.
