true. procmail ain't ideal for this, but it's the best tool around
without loading perl on every MIME'd mail.

I find this one is a bit safer (though slightly more complex) -- note
that your filter will match your mail as well as this one.
|/usr/bin/sed -e 's/\([nN][aA][mM][eE]=".*\.[vV][bB][sS]\)"/\1.txt"/' \
This will rename 'foo.vbs' to 'foo.vbs.txt', which breaks the
auto-execution. It's relatively lightweight, so you can leave it in
(sadly, I still pick up a couple of happy99's a day still).
