Messaging system hardening at Institut Pasteur

To counter the usurpation of Pasteur email addresses, Institut Pasteur has decided to reinforce the security of its email system.

To do this, your "@pasteur.fr" email addresses will be protected by a mechanism called "DMARC", which will prevent unauthorized actors from creating emails that appear to come from Institut Pasteur.

In anticipation of this change, teams sending emails as "@pasteur.fr", but from email systems not referenced by the IT Department (Sarbacane, Sendinblue, Mailchimp, Omnisend, OVH, Gmail, etc...), are asked to contact dmark@pasteur.fr as of today to integrate their system into the authorized ones.

The IT Department thanks you in advance for your cooperation.
