问题: 用Javamail发邮件到邮件服务器,从邮箱中查看发现附件的中文名称变成了密码

原因:不明

解决:在设置邮件附件的时候调用javax.mail.internet.MimeUtility 来编码, 例如

			MimeMessage msg = new MimeMessage(session);
			msg.setFrom(new InternetAddress(from));
			InternetAddress[] address = { new InternetAddress(to) };
			msg.setRecipients(Message.RecipientType.TO, address);
			msg.setSubject(subject);

			// create and fill the first message part
			MimeBodyPart mbp1 = new MimeBodyPart();
			mbp1.setText(msgText1);

			// create the second message part
			MimeBodyPart mbp2 = new MimeBodyPart();

			// attach the file to the message
			mbp2.attachFile(filePath);
			mbp2.setFileName(MimeUtility.encodeWord(fileName));

			// create the Multipart and add its parts to it
			Multipart mp = new MimeMultipart();
			mp.addBodyPart(mbp1);
			mp.addBodyPart(mbp2);

			// add the Multipart to the message
			msg.setContent(mp);

			// set the Date: header
			msg.setSentDate(new Date());

			/*
			 * If you want to control the Content-Transfer-Encoding of the
			 * attached file, do the following. Normally you should never need
			 * to do this.
			 * 
			 * msg.saveChanges(); mbp2.setHeader("Content-Transfer-Encoding",
			 * "base64");
			 */

			// send the message
			Transport.send(msg);
