I'm considering scoring on multi and give the user some freedom, see

The only disadvantage I see from a bigger local skiplist is some local
CPU usage for every uri in a email. Most pc's have plenty of CPU
power ;-) If this could become a problem, I can lower or optimise the
local checking. Are there any other disadvantages?
