楼主是不是少一个包呀:我的程序可以测试通过.
你是不是用到:activation.jar

如果你仍然有这个问题javax.mail.AuthenticationFailedException有可能你的邮箱不能发送，我看我自己原来可以的运行的程序，将邮箱换成chinamail的就是不行，我用126.com的就可以，而且错误跟你的说的错误一样，希望对你有帮助。

这个问题解决了,谢谢大家,
还有一个问题,
props.put("mail.smtp.host", "smtp.163.com");
以上这句批定了用163.com的smtp服务器,那么是不是要这样的局限:
邮件的发送方必须是[email protected],
有这个疑问是因为我试了一下,如果用其他发送地址如[email protected]就不能发送,
请大家赐教!!!
