Hi,
It seems that convertTo7Bit is also plagued by Java bug 4403733 (see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4403733). If a message is multipart all individual parts are converted to 7bit. The problem though is that because of bug 4403733 the changed parts are not persistent. A possible workaround, taken from the bug report, is to add a setContent private void convertTo7Bit(MimePart part) throws MessagingException, IOException { if (part.isMimeType("multipart/*")) { MimeMultipart parts = (MimeMultipart) part.getContent(); int count = parts.getCount(); for (int i = 0; i < count; i++) { convertTo7Bit((MimePart)parts.getBodyPart(i)); } part.setContent(parts); <============================================ setContent added } else { if (part.isMimeType("text/*")) { part.setHeader("Content-Transfer-Encoding", "quoted-printable"); part.addHeader("X-MIME-Autoconverted", "from 8bit to quoted-printable by "+getMailetContext().getServerInfo()); } else { // if the part doesn't contain text it will be base64 encoded. part.setHeader("Content-Transfer-Encoding", "base64"); part.addHeader("X-MIME-Autoconverted", "from 8bit to base64 by "+getMailetContext().getServerInfo()); } } } Is my observation correct?
