美好的一天SO人！

我正在尝试使用gmail smtp服务器通过java代码发送电子邮件很长一段时间了，我仍然不幸获得成功。我尝试执行此tutorial

中的代码

我得到了一个例外。以下是日志跟踪：

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;

我已经搜索了连接异常错误，我尝试了一些建议：

ping smtp.gmail.com - ＆gt;成功。
telnet smtp.gmail.com'port' - ＆gt;不成功。我试过了465和587

网络上还有什么需要做的吗？请帮我解决这个问题。提前谢谢。
