Do you suggest until resolved disable this? If to disable it what exactly do I need to disable?
Upon closer inspection are you sure you fed SA the actual message with complete headers?
Are you sure that's not the output of spamassasin --lint??
It looks like the test message is missing a LOT of headers.. No Subject, no Date, no From:, no Received headers.
Note it doesn't look like it failed to parse the Received: headers.. it looks like the are absent entirely.. There's no complaint about an unparsable Received header in the debug..There's no mention of even trying to parse one...
This part looks very much like --lint:
debug: all '*From' addrs: [EMAIL PROTECTED]
Also suspicious:
MISSING_DATE,MISSING_SUBJECT
