解决方法：


if(this.smtp.indexOf("smtp.gmail.com")>=0)


            {


                properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 


                properties.setProperty("mail.smtp.socketFactory.fallback", "false"); 


                properties.setProperty("mail.smtp.port", "465"); 


                properties.setProperty("mail.smtp.socketFactory.port", "465"); 


            }

或者换发送邮箱

一般邮箱端口号为25   

gmail为465或587
