The biggest problem I saw with the preview pane is it could be tricked into execuiting code on your system even with no attachment present. If
Yeah but that was patched at V5.5 level so it hasnt been a problem in a few years for anyone who updated from lower versions.
you disable all HTML e-mail then you might avoid this but if you receive HTML embedded in your e-mail as most people do now days when using
There was a worse problem at one time where just the existence of an email in your inbox lead to troubles but that was so far back I cant even remember it all, now. You didnt read it, just received it.
Outlook of any version then you are at risk. Even though you may be filtering attachments and be running zone alarm your e-mail client will execute a lot of embedded HTML which basically acts like you are using a browser and visiting somebody's web site to pull the content. That
If you use Zone Alarm to disallow access for OE on port 80, you can overcome that.
Again as I posted before, anything but Outlook 2003 I would recommend against the preview pane.
None of my income is derived from anything other than Microsoft users because that is all the businesses (tiny to small) around where I work use. I have never had an infection problem in any machine I have touched, using their products, since I have been doing their computer work nor has mine ever been infected - which is not to say it wont ever happen of course, just saying that poor old MS suffers the "red car syndrome". Eg, 100 cars on the road, 90 red, the rest varying competing and useless colours. A survey comes out saying that more red cars than any other are involved in fatal accidents therefore red cars are a serious problem on the road. We all know that there are myriads of problems that can affect all computers but the one that is swamping use of any other out in the world is the one that will always get the most hits and the most notoriety as a result. The way *nix is going, there is no doubt in my mind that their day is coming, whether that is only a 5% jump in use or a jump to be nearly a Microsoft. Whatever it ends up at it's peak, it will also be attracting more problems as more people use it. Don't forget, it's usually the nut behind the wheel that causes the problems on the road.
