I understand the first one, but what does the second one do? About
half my daily ndrs have scores higher than 6.3, and I suspect that
is because of the "crediblefrom".

if a spam scores < 6.3, the sender gets a 'bounce' (you might be
a spammer if....)<br>
if it also has valid spf or dkim, and its under 18, the sender also
gets a bounce.<br>
<br>
so, forged spammers < 6.3 will create backscatter.<br>
spammers who spam from valid accounts will get bounces till it
scores 18.<br>
