Challenges

In Luxembourg, teachers benefit from a specific email address ending in @education.lu. This email address managed by the Restena Foundation is easily recognised and shared by all educational establishments.

Features

The Restena Foundation creates professional "@education.lu" email addresses assigned to Luxembourg teachers. This service includes:

  • a professional email account,
  • an institutional email,
  • the option of viewing your messages from any computer connected to the network,
  • anti-virus and anti-spam protection,
  • encryption to ensure the secure traffic of messages,
  • dedicated support and assistance.

Management and hosting options

Two management and hosting options for @education.lu emails are offered to teachers: the Office 365 environment set up by the Centre de Gestion Informatique de l’Éducation (CGIE) to meet national education needs, or the Restena Foundation's email hosting platform.

The Restena Foundation automatically sets up new email addresses with transfer and management in Office 365 (365.education.lu), an environment in which users can read, manage, and send their education.lu emails.

Users may at any time cancel this redirection and migrate the service to the Restena Fondation's email hosting platform. All user accounts created before November 2016 and not migrated to Office 365 are hosted on Restena's servers.

How to benefit?

The allocation of an email address is provided by the Centre de Gestion Informatique de l’Éducation (CGIE). Users do not have to carry out any of the steps themselves. They will receive a letter delivered to their home address notifying them that an account has been set up.

Some useful information

  • Since October 2016, new @education.lu addresses are set up with transfer and management in Office 365.
  • Teachers have the option of setting up their education.lu email addresses to be used exclusively within the Microsoft Office 365 environment.

  • Why can’t I send any e-mails?

    There are multiple scenarios that can block the sending of your e-mails:

    • Incorrect configuration of mail software: Check the name of the outgoing SMTP mail server. This must be encoded as follows: smtp.restena.lu. To help you set up your mail software, view our user manual 'Configure your email access'..
    • SMTP authentication not set (‘inactive’): If the Restena Foundation is not your ISP, SMTP authentication for your e-mail client is required. To make this change, view our user manual 'Configure your email access'.
    • Default port for sending SMTP e-mail is blocked: If the Restena Foundation is not your ISP, you may have trouble sending mail from our SMTP server ‘smtp.restena.lu’. In this case, open the settings of your mail software and change the SMTP port used for sending by replacing 25 (default) with 587. To make this change, view our user manual 'Configure your email access'..
    • Communication blocked by local firewall and other installed security software: Configure your firewall to allow the SMTP gateway to our SMTP server “smtp.restena.lu”. For more information, refer to the documentation of your firewall.

    Tip: You can check your Internet Service Provider with the custom network diagnostics on our Helpdesk page.

  • Why can't I receive (or have stopped receiving) messages in my mailbox?

    There are multiple scenarios that can block the receipt of your e-mails:

    • No network connection: Check that the connection to the internet / network is established correctly.
    • Incorrect configuration of mail software: Make sure you have set up your incoming mail server (mail.restena.lu) and your username, then check that the proprietary Microsoft option ”Login with secure password authentication (SPA)” is not selected.
    • Problem with antivirus software and/or firewall: Check that your antivirus / firewall software is working correctly. Refer to the documentation of your antivirus / firewall software

  • Why is the default port for sending e-mail from my electronic messaging blocked?

    In an effort to limit the volume of SPAM originating from their network, some Internet Service Providers impose a restriction on their clients by blocking the default SMTP port (25) from sending messages to an SMTP server other than those which are part of their own network.

    If the Restena Foundation is not your ISP, you may have trouble sending mail from our SMTP server ‘smtp.restena.lu’. In this case, open the settings of your mail software and change the SMTP port used for sending by replacing 25 (default) with 587. To make this change, view our user manual 'Configure your email access'.

    Note: Users connected to the internet via the Restena Foundation’s ‘DSL/Fibre Access’ service and users of the Webmail service are not affected by this restriction.
