These two are mostly used by spammers. So, if you have certain spam evaluation criterias, you can construct something of them.

Well, that's probably what the bayes filter internally does.

Now... how should I achieve that... I get points from 0.00000000 to 
0.99999999. Harmless text range around 0.5 or a bit above. If I 
"normalize" that to 1..10 I get points a bit higher than spamassassin 
(From what I know there score 3 is normally SPAM, above 10 it's always).

No matter what I do; the behaviour will be different from Spamassassin. 
I really think about the extension "spamdetection" which might be good 
to level several sources the way they give a reliable scoring system. 
Thats the way spamassassin works. The Bayes-Filter there is giving out a 
percentage and SA seems to give them points based on percentage-ranges 
(i.e. 0 to 10% = -1 Point, 10 to 30% 0.1 Point, 30 to 50 % 0.5 Points...).

Of course any extension might access spfgblib directly as long as it 
takes in account the way it behaves.

I installed spamdetection. From the first look it apparently uses rules 
and blacklists. That's a good idea and can be combined with external 
sources. Does it already do scoring? I think I will do my first steps 
touse the ASP spfgblib somewhere with that extension. The resulting 
thing will probably be a PHP-snippet which should be usable elsewhere too.

If you work with score you need that, of course.
