Guillermo Grandes commented on JAMES-648:
-----------------------------------------

Well, I have reviewed the problems, and I have found a small "sanitizer" for extrange Mails:

    try {
        MimeMessage message = (Mail)mail.getMessage();
        // Sanity of "Content-Transfer-Encoding" (non-existent header)
        if (message.getHeader("Content-Transfer-Encoding") == null) {
            BufferedInputStream is = new BufferedInputStream(message.getRawInputStream());
            while (is.available() > 0) {
                if (is.read() > 0x7F) {
                    log.warn(mail.getName() + ": 8bit Stream");
                    message.setHeader("Content-Transfer-Encoding", "8bit");
                    break;
                }
            }
            is.close();
        }
        // Sanity of "Content-Type" (multiple Content-Type headers)
        String [] heads = message.getHeader("Content-Type");
        if ((heads != null) && (heads.length > 1)) {
            message.setHeader("Content-Type", heads[heads.length-1]);
        }
        message.saveChanges();
    } catch (javax.mail.MessagingException me) {
        log.error("MessageingException", me);
    }

This piece of code can be used as Mailet.
