[exim] Misplaced Content-Type

Hello, all.

Possible stupid question, but....
I received many spammer emails with wrong placed MIME/Content-Type like


Message-ID: <7321584745.0020673893@???>
Date: Fri, 26 May 2006 22:15:31 -0500
To: <user@???>
Subject: No Forms All orders filled V|AGR@ :can
MIME-Version: 1.0
Content-Type: Multipart/related;
type="multipart/alternative";
boundary="------------E4346146.01AB82D1"

After Subject must be CRLF according to RFC.
Can i filter such messages by acl_data?
