If you are a Deutsche Telekom customer and use a Speedport router, you may experience problems when sending emails via your email account. This is because Speedport routers often only allow emails to be sent via a predefined list of ‘secure’ email servers and block other servers.
In this article, you’ll learn how to configure your SMTP settings in the Telekom Speedport router so that emails can be sent securely and reliably via our SMTP servers. It’s particularly important that your emails arrive without any issues, especially when security warnings or error messages occur.
Background
By default, some Speedport routers (and other router models) block certain SMTP ports or monitor SMTP traffic to prevent unauthorised email sending and spam. To ensure that emails can still be sent securely, in some cases an exception rule or a list of trusted SMTP servers must be set up. SpeedIT Solutions offers its own SMTP servers for this purpose, which you can configure in the settings of your Speedport router.
Prerequisites
- Login details for your SpeedIT Solutions email account You will need the username (email address) and password for the email account you have set up with us.
- Speedport router Ensure that you have access to the configuration menu of your Speedport router. You can usually access this via the address http://speedport.ip in your web browser. If you do not know your login details, please refer to your contract documents or the type plate.
- Information about our SMTP server
- You can find this information in the web server control panel for your hosting/server with us.
(The exact server address and port details may vary depending on the product you have with us. Please check the documentation for your email product or contact our support team.)
Step-by-step guide
1. Access Speedport
- Open your web browser (e.g. Chrome, Firefox or Edge).
- Type http://speedport.ip into the address bar and press Enter.
- Log in using your device password. You’ll usually find this on the back of your Speedport router.
2. Settings for email or list of secure SMTP servers

- Look for options such as ‘List of secure email servers’, ‘List of secure SMTP servers’ or ‘Advanced email handling’.
- If available, add the mail server from your Control Panel.
- Save the settings.
3. Configure your email programme
- Open your email programme (e.g. Outlook, Thunderbird) on your computer.
- Under ‘Outgoing server (SMTP)’, enter the details for your mail server.
- Enable encryption (SSL/TLS or STARTTLS) and save the changes.

Tip: Check your firewall and antivirus settings
Some security programmes or firewalls may also block SMTP traffic. Make sure that these programmes do not block the SMTP port (465 or 587). Also check whether your antivirus programme has activated a special email protection feature that configures the ports differently.
Common causes of errors
- Incorrect login details: Make sure that the username and password are entered correctly.
- Missing SSL certificate: Always use the correct encryption. For SSL/TLS, port 465 and the corresponding certificate must be correct.
- Router update required: On older Speedport models, a firmware update may be necessary for the list of secure SMTP servers to be displayed.
Conclusion
The list of secure SMTP servers in your Speedport router is a feature designed to ensure that emails can be sent via trusted providers - without connection issues or security warnings. With SpeedIT Solutions’ SMTP servers, you benefit from high reliability, fast response times and comprehensive security standards.
