# How do I create a mailbox on Faaaster?

Mailboxes are managed from the **Emails** section of the left menu, once an Email subscription has been taken out on the domain.

## Creating a mailbox

1. Open the **Emails** section of the left menu.
2. Select the domain in question.
3. In the **Mailboxes** section, click **Create mailbox**.
4. Fill in the **Username** (the part before the `@`), the **Password** (at least 8 characters) and the allocated **Storage space**.
5. Click **Create mailbox**.

The counter at the top of the section ("1 / 2") shows the mailboxes used out of the number included; the **Create mailbox** button is grayed out once the maximum is reached.

Each mailbox's space is set independently, within the limit of your subscription's total quota. You can change it at any time afterwards.

> **Split the space according to actual use.** A `contact@` mailbox that receives attachments needs more than a `billing@` that archives nothing.

## Accessing your messages

**Webmail** is the simplest option: the **Webmail** entry in each mailbox's action menu (the **…** icon at the end of the row) opens it in the browser. Nothing to configure.

## Setting up a mail client

For Apple Mail, Outlook, Thunderbird or a phone's mail app, the **Configuration** entry in the mailbox's action menu opens the **IMAP/SMTP Configuration** window:

**IMAP (incoming)**

| | |
| --- | --- |
| Server | `mail.faaaster.net` |
| Port | `993` |
| Security | SSL/TLS |
| Username | your full email address |

**SMTP (outgoing)**

| | |
| --- | --- |
| Server | `mail.faaaster.net` |
| Port | `465` |
| Security | SSL/TLS |
| Username | your full email address |

The password is the mailbox's password.

> **The username is the full address**, not just the part before the `@`. It's the most common mistake during setup.

> ℹ️ **Faaaster support does not cover the configuration of third-party clients.** The settings above are complete and work with any IMAP-compatible application; if you run into a problem specific to Outlook or Apple Mail, webmail remains available with no setup.

## If messages don't arrive

First check your DNS records: without properly propagated **MX** and **SPF** records, the mailbox exists but receives nothing. The **DNS** section of your email account shows how many records are valid ("5 / 7 valid records") and details each one; the **Refresh** button re-runs the check.
