Email Security

When sending an email to IEA, the email address of the sender is used only for correspondence with the particular sender. When sending an email with content worthy of protection, we strongly recommend encrypting it in order to prevent unauthorized notice or falsification on the transmission path. The type of encryption must be coordinated with IEA. Should the sender not wish to receive an answer via email, another way of communication must be mentioned explicitly.
