    Well, the problem that many people will have with these sorts
    of e-mails is known in the trade as Microsoft Outlook. What
    really scares me is that *simply clicking* on such an e-mail
    in Outlook, loading it up in the AutoPreview page, which many
    people regard as "safe" (scripts aren't allowed to run in it),
    will cause the bug to be loaded and your address to be verified.
    
    The most scary bit is that I don't think there is any way to 
    disable remotely-loaded images in Outlook. True, you can choose 
    which Internet Explorer Security Zone recieved messages fit into,
    but I don't think that even the "Restricted Sites" zone disables
    off-site image loading (I'll have to check on that one, the help
    isn't very clear).
    
    So, where does that leave a user? In Outlook, you can't tell if 
    an e-mail is HTML without viewing it in the preview pane, in 
    which case you've already confirmed your existence to spammers. 
    You can't report the spam using such services as SpamCop unless 
    you actually open the e-mail to get the source. Now you're 
    gambling. Staring at this spam, betting as to whether it's html 
    or text. But to *delete* the thing immediately, you need to 
    select it, and in selecting it, you are loading it into the 
    preview pane.
    
    I've turned off my preview pane to start with. And I think a 
    script which warns you of (or preferably deletes) HTML e-mails
    before they are loaded needs developing. 
    
    
    Cheers,
