		props.put("mail.from", from);//设置邮件源地址
		Session session = Session.getInstance(props, new MailAuthenticator(from, "your password"));//获取邮件会话对象
		session.setDebug(true);//启用调试信息

			msg.setFrom();使用InternetAddress.getLocalAddress方法设置RFC 822 "From" 头域
			msg.setRecipients(Message.RecipientType.TO, to);//设置收件人
			msg.setSubject("JavaMail hello world example");//设置邮件主题
			msg.setSentDate(new Date());//设置邮件发送时间
			msg.setText("Hello, world!\n");//设置邮件内容
			Transport.send(msg);//发送邮件
