Localisation par e-mail

Je suis pas sûr car si c'est l'adresse IP du serveur qui est envoyée tu ne verras pas d'où il s'est connecté mais où se situe son serveur de messagerie.

Merci beaucoup pour vos réponses nombreuses et rapides !!!
Je vous copie le message en-dessous. Je ne suis pas sûre d'avoir trouvé l'IP. J'ai essayé tout ce qui ressemblait de près ou de loin à un IP et j'ai fait une recherche mais ça ne donne rien.
Peut-être vous pourrez me dire quel est l'IP de ce ftorreiro@gmail.com en lisant son message.
Encore merci.
