Thank you Paul for your exact and precise analysis.
I work for CFR and confirm that this email is a fraud , that it was not sent by us.
Do not pay or open the links indicated.
CFR has filed a complaint at the authorities about this.
We do work for many major companies for collection in France, and the hoax uses an old version of email with a few changes.
Best regards,
Thomas Vergeat
