詳細
Changes the local part — `sales@example.com` becomes `hello@example.com` — with every message already in the mailbox intact. ⚖️ Part of the owner's 2026-08-16 ruling that a domain owner must be able to *"create the mailboxes easily and manage them in full"*. **A POST to a sub-resource rather than a field on `updateMailbox`, deliberately.** A rename moves where mail is delivered; a quota edit does not. Sharing a body would let a mistyped field change a customer's address as a side effect of resizing their mailbox, and would make the two indistinguishable in the audit log. ⛔ **The engine reads the mailbox back from the backend and refuses if the address did not actually change**, rather than trusting the backend's success response. It never falls back to create-then-delete: that would "work" on screen and silently destroy every stored message. `409` when the target address already exists on the domain; `422` for a mailbox that has not finished provisioning, and for the `system_managed` address the site sends from. Requires `mail.manage`.

local | string | はい | The part before the `@`. |
quota_mb | integer | はい | This mailbox's size in MB. `0` means no cap. |
used_mb | integer | はい | How much of it is used, as the mail backend last reported it (#932). Refreshed by the hourly reconcile, so it is a recent figure rather than a live one. |
percent_used | integer | はい | How full, 0-100. Always `0` for an uncapped mailbox — a percentage of "no limit" is meaningless, not zero-ish. Read `usage_checked_at` before showing it: this is also `0` for a… |

system_managed | boolean | はい | **We** created this mailbox when the domain was provisioned; the customer did not ask for it. It is the address the site itself sends from, so `deleteMailbox` and `renameMailbox… |
