Hello,

it looks like SA doesn't really like partial messages, like
those sent by outlook

these messages have a header, for example

Content-type: message/partial; number=2;
id="[EMAIL PROTECTED]";
 total=18

SA seems to consider what follows (which is a base64 part of
the full message) as text, so it applies any rules to it, which can
often hits
bayes_99, bayes_90, large_hex, obfu,  etc...

known bug ?

Would it be wise to implement a negative scoring rule to offset
those mismatches ? or would there be any drawbacks ?

of course this rule should not match for a supposed partial message with
only
one part :

Content-type: message/partial; number=1;
id="[EMAIL PROTECTED]";
 total=1

Thank you
