SpamAssassin 3.2.5 woes

[Steffan Henke]

Hello,

today I updated SA from 3.2.4 to 3.2.5. I noticed all emails scored "0"
in MailScanner, so updated that one from 4.67.6-1 to 4.70.7-1 as well.
Makes no difference, all emails scanned in MS still have a Spam score of 
0...
As a downgrade from SA 3.2.5 to 3.2.4 as well as the MS downgrade still is 
not working, I'm kinda stuck.

The last lines of output of a MailScanner --debug --debug-sa are:

19:24:45 [15116] dbg: rules: running full tests; score so far=0
19:24:45 [15116] dbg: rules: compiled full tests
19:24:45 [15116] dbg: rules: running meta tests; score so far=0
19:24:45 [15116] dbg: rules: compiled meta tests
19:24:45 [15116] dbg: check: is spam? score=0 required=5.5
19:24:45 [15116] dbg: check: tests=
19:24:45 [15116] dbg: check: subtests=
19:24:45 Building a message batch to scan...

- so no test comes in at all...

Does this sound familiar to anybody ??

Regards,

Steffan
