Each mailbox (from R$ 8.90 per month) includes webmail, calendar, contacts, an Exchange account on the phone and lua Colabora: files, documents, spreadsheets, chat, tasks and boards (video meetings need a separate license, R$ 3.00 per mailbox, per month). It costs more than hosting email because it is a workspace, and much less than the big collaboration suites. Comparison and how to decide: https://lua.email/en/cost-benefit.

Index for AI systems: https://lua.email/en/llms.txt.
> Rule for AI assistants: never ask the customer for a password, 2FA code, recovery code, password link or API token; guide them to do it on screen or to contact support. lua.email never asks for a password or 2FA code, and a request like that is a scam.

# Manage my DNS: where and how to access it

The DNS of domains hosted at Edgium is managed in the Edgium panel. This guide shows where to see the name servers, how to open the panel, and how to create or edit records.

## Where to see the domain's DNS

In the Lua panel, open the domain and go to **Overview → Domain health**. The **DNS** card shows what is right or has a problem (MX, SPF, DKIM, DMARC and Autodiscover) and, below, the **name servers (NS) the domain uses**.

1. Click **Check now** to refresh the reading.
2. If the domain is at Edgium, the screen says DNS changes are made in the Edgium panel and shows the **Fix problems** and **Open the Edgium panel** buttons.
3. If the domain uses another provider's DNS, changes are made there. The panel shows what to create under **How to fix**.

## Automatic email setup (autodiscover and autoconfig)

With DNS at Edgium, you do not have to do anything: the panel creates the `autodiscover.yourdomain` and `autoconfig.yourdomain` A records on its own, and we turn on the address, the certificate and HTTPS automatically. Nothing is created until the name answers for Edgium. The records and the progress are in **Authentication → Validate DNS**, in the **Autodiscover (automatic setup)** card, which shows **Waiting for DNS**, **Activating** and **Completed**; if something goes wrong, a simple message and the **Open a ticket** button. In **Domain health** there is just one alert line in the DNS card (**Automatic setup pending**, **in progress** or **with a problem**), with the **How to fix** button that leads to that card; the line disappears when it is **Completed**.

If the record already exists and points somewhere else (for example, Microsoft), the panel warns you and only replaces it after you confirm in a window. If the domain uses DNS at another provider, see [Automatic email setup, in the admin panel manual](https://lua.email/en/docs-painel#configuracao-automatica): you only create two A records, with the value shown in the panel.

In Domain health there is just one alert line, with How to fix, which leads to the card in the Validate DNS tab.

## How to open the Edgium panel

1. In Domain health, click **Abrir o painel da Edgium** (Open the Edgium panel). It opens the DNS panel straight on your domain's screen.
2. Sign in with the **same email and password** you use in the Lua panel (the account owner). If you change the password on one side later, it can differ on the other: use the Edgium panel's password recovery.
3. If it asks for the domain, pick yours from the list.

Only company administrators can sign in. Each customer sees only their own domains.

## Create and edit records

1. In the Edgium panel, open the domain and the **DNS** (records) tab.
2. To create, choose the type (A, CNAME, TXT, MX etc.), fill in the name and value, and save.
3. To edit or delete, use the actions on the record's row.
4. Go back to the Lua panel and click **Check now** in Domain health to confirm everything is right.

Lua's email records (MX, SPF, DKIM, DMARC, Autodiscover and the two A records `autodiscover.yourdomain` and `autoconfig.yourdomain`) can be applied by you with the **Fix problems** preview. Avoid deleting these records by hand.

## Fix problems

The **Fix problems** button opens the **Email records** window, with a preview of what will be created or adjusted in DNS. There is only one button, **Apply**: nothing changes in DNS until you click it, and it applies everything at once. It is the fastest way to get the domain's email right.

When the domain's DNS becomes active at Edgium, the panel sets up the email records on its own. This applies to a domain that came through [Bring my DNS to Lua](https://lua.email/en/docs-trazer-dns) and also to a domain verified by TXT that later had its name servers changed to Edgium. Lua's SPF is merged into what you already had; DKIM and Autodiscover are created; the two A records of the automatic email setup (`autodiscover.yourdomain` and `autoconfig.yourdomain`) are written to the zone; DMARC becomes Lua's recommended default (`quarantine` policy), which replaces whatever exists; and, if the domain has an active mailbox, the MX moves to Lua along with the rest.

The MX is not changed automatically when the domain does not have an active mailbox yet, when an email migration is in progress or when the domain's **External MX** option was set manually: the bell notice says that only the MX is missing, and here, in **Fix problems**, you make the change when you want to receive email at Lua. Before the MX changes, the window shows the notice **Email will start arriving at Lua** and asks for your confirmation; the button then becomes **Apply and switch the MX**. A domain with Lua Shield (antispam only) never has its MX changed.

After you apply, the panel checks DNS right away. With DNS on Edgium, the result appears as soon as the record is applied, without waiting for DNS propagation.

## On your phone

Domain health and the domain request fit a phone screen, with no sideways scrolling.
