When defining a filter in KMail 1.5.3 (Debian unstable), there are only enough entry boxes sufficient to define two criteria. There are no "More" or "Fewer" buttons in the criteria section. I can define multiple Actions with the "More" or "Fewer" buttons in the Action section, however. How can I define more than three criteria? (I'm trying to implement a 'white-list' method of filtering.) -- Comments are appreciated, Bob
