note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs.我关闭过防火墙，网络连接正常，但是怎么也连接不上SMTP服务器，请高手们指点！

解决方案 »

  1.   

    props.put("mail.smtp.host", smtpHost);不是prop.put("mail.host",host);
    props.put("mail.pop3.host", popHost);
    props.put("mail.smtp.auth","true");
    只要有以上3项就能收发email了,当然要重写验证哪个类.
