I think you're missing the most dangerous messages with this. Namely
html-mails with some script code embedded. Of course you can't block html
mails (even though I would like that).

IMHO these are far more dangerous, because you don't need to open any
attachement. On the other hand, I think M$ fixed that bug in OE...
