Hi everybody,
I'm using spamassassin 3.3.2, along with postfix 2.6.6 and amavisd-new
2.8.0.
The system spamassassin is running on is used primarily for URIDNSBL checks.
Recently I had some messages classified as spam because of these rules:
X-Spam-Report:
* 1.2 TO_MALFORMED To: has a malformed address
* 0.5 NULL_IN_BODY FULL: Message has NUL (ASCII 0) byte in message
* 0.1 MISSING_MID Missing Message-Id: header
* 1.8 MISSING_SUBJECT Missing Subject: header
* 1.4 MISSING_DATE Missing Date: header
The problem is that the body is not null at all, and headers aren't
missing: what happens here is that the To: header contains chinese
characters that are not in encoded word format and that interfere with
spamassassin's parsing.
This is a problem because the mail body can't be checked against other
rules.
Is there a way to fix this, other than changing MUA's behaviour to
encode the message properly? How can I have spamassassin to parse the
remaining part of the message in such conditions?
