If you try to access WebMail.Aeronautica.difesa.it, the browser gives a warning that the website's security certificate may not be valid or that this may be an attack site. The warning reads:

"You attempted to reach webmail.aeronautica.difesa.it, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications."
