+### Create a Subdomain Mailbox Address
+
+If your base domain is already configured in `DOMAINS` / `DEFAULT_DOMAINS` / `USER_ROLES`, and
+`ENABLE_CREATE_ADDRESS_SUBDOMAIN_MATCH` is enabled (it can also be toggled in the admin panel),
+the create-address APIs can accept subdomains directly:
+
+```python
+res = requests.post(
+    "https://xxxx.xxxx/admin/new_address",
+    json={
+        "enablePrefix": True,
+        "name": "project001",
+        "domain": "team.example.com",
+    },
+    headers={
+        'x-admin-auth': "<your_website_admin_password>",
+        "Content-Type": "application/json"
+    }
+)
+```
+
+- If `example.com` is an allowed base domain, `team.example.com` and `dev.team.example.com` can match successfully
+- Lookalike domains such as `badexample.com` will **not** be treated as `example.com`
+- This is different from `RANDOM_SUBDOMAIN_DOMAINS`: here the caller **explicitly specifies** the subdomain, instead of the system generating a random one
+- In the admin panel, this can be set to **Follow Environment Variable / Force Enable / Force Disable**. Choosing **Follow Environment Variable** clears the admin override and returns to env fallback behavior.

+## Let APIs Specify Subdomains Directly
+
+If you do not want the system to generate a random subdomain, and instead want the caller to
+explicitly create addresses like `team.abc.com`, enable:
+
+```toml
+ENABLE_CREATE_ADDRESS_SUBDOMAIN_MATCH = true
+```
+
+When this is enabled, as long as `abc.com` is in the allowed base-domain list, the following
+addresses can be created through `/api/new_address` or `/admin/new_address`:
+
+- `name@team.abc.com`
+- `name@dev.team.abc.com`
+
+> [!NOTE]
+> This only relaxes the domain validation used by the create-address APIs. It does not change the
+> default domain dropdown, and it does not create Cloudflare-side subdomain mail routes for you.
+>
+> If the admin panel has already saved an override once, you can switch it back to **Follow Environment Variable** to clear the override and return to env fallback behavior.
