# Send Email Alerts from Synology and QNAP NAS with mySMTP

> Configure mySMTP on Synology DSM 7 and QNAP QTS / QuTS NAS devices. Set server, port 587, TLS, and credentials for notification emails.

## SMTP settings

| Setting | Value |
| - | - |
| Server | Your dedicated hostname from the setup email, e.g. `relayxx.mysmtp.com` |
| Port | **587** |
| Security | **STARTTLS** |
| Authentication | SMTP username and password from mySMTP |

<Note>
  Server (shared IP, DK only) | `mail.mysmtp.com` / Shared IP plans are only available to customers in Denmark.
</Note>

<Tip>
  Use the exact relay hostname from your setup email. `relayxx.mysmtp.com` is only an example.

## Troubleshooting

* **Test email fails:** double-check the server name is copied exactly from the setup email, and that the username and password are correct.
* **Connection error on port 587:** your network may block it. Try port **2525**.
* **Sender address rejected:** make sure the sender email uses a domain authenticated for your mySMTP account. See [DNS settings quick explainer](/getting-started/dns-settings-quick-explainer).
