Email and messaging

Email and Messaging

Campus / Ecole polytechnique mail system

EDU address

You can have a firstname(P)lastname(Q)polytechnique(P)edu email address if you wish.

It is just a pointer which does not contain any emails but redirects your messages to a mailbox where your emails are stored. This box can be managed by the IT department of X. It expires when you leave the School.

Warning

We strongly advise against forwarding messages destined for your polytechnique.edu address to a third-party mailbox such as Gmail, Yahoo, Hotmail and others. At the scale of the École polytechnique, these transfers affect the reputation of the polytechnique.edu domain each time the promotion or site mailing lists are used, with the consequence of a degradation in the handling of emails from the School by the most common courier services. For this we ask you to transfer to an institutional type address (university, higher establishment, etc.)

Zimbra

Zimbra

The mailboxes managed by the IT department of Ecole polytechnique operate under Zimbra.

Each person in the XAJAM directory of the Ecole polytechnique could have an account on this server.

It suffices to delete a user from the directory to trigger the deletion of his mailbox.

This deletion is most of the time subject to an expiration date informed in advance by the secretariats of the various departments.

Before it occurs, several closure notification emails are sent to the user.

Warning

Your zimbra mailbox associated with this account will continue to function for another 2 weeks. After this period your access to the mailbox will be blocked. Finally, after 6 weeks, the mailbox will be permanently deleted.

Note that :

  • mailboxes have a default size of 10 GB.
  • the maximum size of attachments that can be sent is 20 MB

The use of webmail is to be preferred as much as possible; access by the URL: https://webmail.polytechnique.fr

Please note that in the Preferences tab, you can modify :

  • signatures
  • Filters (equivalent to Outlook rules)
  • Out-of-office messages

You can find more documentation here

Note

Username = firstname.lastname + XAJAM password

Warning

We will never ask you, in a message, to provide us with confidential information (access code, password, etc.). If so, it would be a phishing email that should be deleted without responding.

CNRS mail system

CNRS mail

All CNRS staff have a mailbox, with an institutional address of the form firstname(P)lastname(Q)cnrs(P)fr, hosted on the CNRS email platform.

To access to this service, you must have a CNRS JANUS ID.

You can find documentation here.

Tchap - Simple instant messaging tool

Tchap

Tchap is a secure instant messaging application designed primarily for public servants. Staff at the Ecole Polytechnique and its laboratories are eligible for this service.

It is designed to replace applications widely used at the very top of the French government, such as Telegram and WhatsApp, which are considered unsafe, and whose developers and servers are not under French sovereignty.

To access to this service you have to use your School ID.
