# Email on Windows hosting: create a mailbox and connect your app

> Set up email at your domain on HyperDC Windows hosting: point the domain, create a mailbox in the client area and add it to your mail app over IMAP and SMTP.

Difficulty: Beginner

Your Windows hosting plan includes email at your own domain. You create mailboxes in the **Mail** tab of your service page and read them in your mail app or in webmail.

## Step 1: Check your mail domain

Open **Mail**. The **Mail domains** panel lists your domains.

If a domain shows **Waiting For DNS**, its mail starts when the domain points to the server. Point the domain's A record to the **Server IP address** shown on **Overview**; see [point a domain to your server](/guides/point-domain-to-server). Mail then switches on by itself, with DKIM signing.

## Step 2: Create a mailbox

1. Under **Mailboxes**, choose the domain and select **New Mailbox**.
2. Enter the **Name before @**, such as `info`, and a **Password**.
3. Check **Size (MB)** and select **Create Mailbox**.

**Verify:** the address appears in the list.

## Step 3: Add it to your mail app

Open the **Mail client settings** panel in the same tab and copy the values into your mail app:

| Setting | Value |
|---|---|
| Incoming mail | **Incoming (IMAP)** from the panel, port 993 with SSL/TLS |
| Outgoing mail | **Outgoing (SMTP)** from the panel, port 465 with SSL/TLS or port 587 with STARTTLS |
| User name | The full mail address |
| Password | The mailbox password |

**Verify:** send a message from this mailbox to itself and read it in your mail app.

## Use webmail

You can also read and send mail in your browser, without a mail app:

1. In **Mail**, select **Open Webmail**.
2. Sign in with the full **E-mail Address** and the mailbox password.

Your folders are Inbox, Drafts, Sent, Archive, Junk and Trash.

- **Reading:** HTML mail is cleaned before you see it, and images from other sites stay blocked until you select **Show Images**.
- **Sending:** you can attach files, within the 50 MB limit, and a copy goes to Sent.
- **Tidying up:** you can flag several messages at once, and **Delete** moves a message to Trash.
- **Leaving:** on a shared computer, select **Sign Out** when you finish.

**Verify:** the message you sent in step 3 is in your Inbox.

## Troubleshooting

**The mail app cannot sign in.** The user name must be the full address, not only the part before `@`.

**The domain stays on Waiting For DNS.** Check its A record. Changes can take a while to reach the whole internet.
