            InternetAddress[] tos = new InternetAddress[1];//收件箱
            tos[0] = new InternetAddress("[e-mail]");
           
            msg.setRecipients(RecipientType.TO, tos);
            msg.setSubject("这是一个测试邮件。");
            msg.setContent("这是测试邮件的内容", mailtype);
            Transport.send(msg);
            result = true;
        } catch (Exception e){   
           e.printStackTrace();
        }

    }
    
    
    public static void main(String [] args){
