		try {
			msg.setText("来自hbiao68@@yeah.net 的 邮件测试");
			msg.setSubject("测试邮件");
			msg.setFrom(new InternetAddress("hbiao68@yeah.net"));
			
			msg.setSentDate(new Date());
			//添加附件必须设置邮件类型
			MimeMultipart msgMultipart = new MimeMultipart("mixed");
			msg.setContent(msgMultipart);
			
			MimeBodyPart attch1 = new MimeBodyPart();
			msgMultipart.addBodyPart(attch1);
			
			//设置附件的名称
			attch1.setFileName("file1.BMP");
			//设置数据源（即数据的来源）
			DataSource ds1 = new FileDataSource("C:\\d.BMP");
			DataHandler dh1 = new DataHandler(ds1);
			//设置附件的句柄给这个附件对象
			attch1.setDataHandler(dh1);
			
			Transport transport = session.getTransport();
			transport.connect("smtp.yeah.net", 25, "用户名", "密码");
			transport.sendMessage(msg, new Address[]{new InternetAddress("939706250@qq.com")});

			transport.close();
		} catch (MessagingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}

}

  

这里根据邮件的内容需要配置邮件的类型，如图：（来自传智播客）
