Change in spam processing

[Stephen Davies]

Today, amavisd on my mail server changed the way it processes spam.

Before today, spam headers in clean emails looked like:

X-Bogosity: Ham, tests=bogofilter, spamicity=0.000000, version=1.2.4
X-Virus-Scanned: amavisd-new at sdc.com.au

because I have configured it to use bogofilter as it's spam filter.

Emails detected as spam by bogofilter were quarantined and never hit an inbox.

Today, the headers have changed to:

X-Virus-Scanned: amavisd-new at sdc.com.au

for clean emails and

X-Virus-Scanned: amavisd-new at sdc.com.au
X-Spam-Flag: YES
X-Spam-Score: 3.354
X-Spam-Level: ***
X-Spam-Status: Yes, score=3.354 tagged_above=0 required=3
	tests=[ALL_TRUSTED=-1, HTML_MESSAGE=0.001,
	HTML_TAG_BALANCE_BODY=0.712, LOTS_OF_MONEY=0.001,
	MIME_HEADER_CTYPE_ONLY=1.996, MIME_HTML_ONLY=1.105,
	MISSING_HEADERS=1.207, RP_MATCHES_RCVD=-0.668]
	autolearn=no autolearn_force=no

for what it thinks is spam (but isn't).

I have not touched the amavisd configuration since February last year and 
amavisd has not been updated since last month.

What else can have changed?

Cheers and thanks,
Stephen
