------解决方案--------------------
你没有设置端口吧
------解决方案--------------------

org.apache.commons.mail.EmailException: Sending the email to the following server failed : mail.bnu.edu.cn:25

这个错误明显是说你的程序发送邮件到 mail.bnu.edu.cn 的 25 端口,发生了错误。这还没到你的邮件代码呢。去检查一下你的机器是否可以访问mail.bnu.edu.cn这个域名,你的机器到mail.bnu.edu.cn的25端口是否畅通。最简单的方法:telnet一下

C:\Windows\System32>telnet mail.bnu.edu.cn 25

经过测试,我这里是可以telnet成功的。
