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！
[解决办法]
我不是绝顶高手所以。。。。。。。。。。。。。。。。。
[解决办法]
顶！
同样的问题！
[解决办法]
顶,同样的问题
[解决办法]
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.
[解决办法]
Could not connect to SMTP host: smtp.163.com, port: 25
服务器地址没错吧。。。
[解决办法]
不知道这个可以不可以!~
