yes, you are right, at the moment we show some results with deep header
checks. The stats belong to the corresponding Spamassassin config. If you use
the -lastexternal with a appropriate trust path, the False Positive rate may
decrease.

I wouldn't say so ;-). We try to provide proper results for ham measurement
corresponding to the displayed Spamassassin config and of course we are useing
"live" data and update the statistics every monday. Some RBL's are currently
shown with the -lastexternal option, like Spamhaus or CBL as explicitly
recommended on the blacklist webpage.
If you would like us to show the -lastexternal results for all lists,
please let me know.
Regards,
Bjoern
