Summary: message/partial misclassified

Initial Comment:
Partial messages (usually split by SMTP limiters) can
have base64 data without appropriate MIME header,
therefore all data will be tokenized and will most
likely result in numerous
 'skip:q 70': 0.98; 'skip:g 70': 0.98;
        'skip:j 70': 0.98; 'skip:o 70': 0.98; 'skip:v
70': 0.98;
        'skip:k 70': 0.98; 'skip:s 70': 0.98; 'skip:t
70': 0.98;
        'skip:a 70': 0.99; 'skip:n 70': 0.99; 'skip:p
70': 0.99;

that will raise its spam score to the roof and cause
the message to go to 'unsure' if the sender is
well-trusted, or to 'spam' otherwise, where it can be lost.

The classifier would do a better job by caching the
classification of messages
containing a header like

Content-Type: message/partial; total=2;
id="01C50EFC.CA6C2680 at quake"; number=1

and applying it to the subsequent parts.

Or, simpler, treat the body of continuation messages as
"empty" .
