So the culprit was a procmail filter which rewrites incoming mail. The
standard report looks just fine with the filter disabled:
X-Spam-Report:
--------------------------------------------------------------
pts rule name description
---- ----------------------
------------------------------------------------
-1.0 ALL_TRUSTED Passed through trusted hosts only via SMTP
-1.9 BAYES_00 BODY: Bayes spam probability is 0 to 1%
[score: 0.0000]
5.0 GTUBE BODY: Generic Test for Unsolicited Bulk Email
I totally forgot about it. Damn! Sorry for all the commotion.
