Computer Security

  1. Hi People,

    From some of my mailing lists that I receive, it is clear that on
    downloading the email only some activation code comes down. Then when I
    double click to open the email the main body of the email gets downloaded.
    How is this done and is it a security risk?

  3. Hi "John".

    Don't know what you mean. Silicon Graphics? Running XP Home. My mate
    using a different computer has confirmed the same. I think it is

  4. I'm not 100% sure exactly what you mean. From what you said I'm assuming
    that the email is simply in HTML and that's what's downloading when you
    open the email. If it is only HTML you can disable it so the message
    will display in plain text, but this all depends on your mail client etc.

  5. Hi Stephen'

    My mail client is Outlook XP. Running XP Home.

    I keep myself informed of the USA space missions by receiving regular
    reports from Unlike other email, when I open these JPL emails only
    then is the message downloaded. Is this a security risk?

  6. Coming from someone like that then it's almost certain to be HTML. All
    this means is that instead of sending plain old text emails they are
    sending the email contents as a HTML page (just like a web page). That's
    what is downloading when you open it, all the pretty pictures etc. No
    different than if you went to their site and opened their page in your

    Security risk? Possibly. Being HTML it can contain scripts, applets,
    etc, etc. I don't use Outlook XP so I'm not 100% sure, but you should be
    able to turn a lot of this stuff off so it doesn't do anything. In your
    email settings there should be options to disallow ActiveX controls,
    VBScript, etc. Hunt around in the settings. But then using a MS email
    client I wouldn't be 100% certain it would work or be safe anyway :)

    It's up to you as to whether you trust the source of these types of
    messages really, coming from JPL there shouldn't be too many issues, but

    Do a quick Google and you should be able to come up with quite a lot of

  7. Thanks for the definitive answer! I do trust the NASA site, but was at a
    loss working out what was happening.

    Thanks again
