[Evolution] complex boolean like filter rules

[Aristotle <aristotle internode on net>]

Hi,

I would like to add complex rules - with if and or type statements but I
can only find where to add a bunch of rules and apply by all being met
or at least one.

Any idea who to make this a little more flexible?

Say to the effect of if (mail containing A or B or C) but NOT (D or E or
F) and so on
