你好 我最近也遇到了这个问题 请问有什么办法解决吗？请告知方法 不胜感激....

上面那个回复已经说了，在那个stackoverflow问答的回复里有方法：
After netease blocking your own client, they will send you an email named 网易邮箱提醒：阻止了一次不安全的收信请求 by mail@service.netease.com.
On the bottom of the email, they provided a link to the configure page:
http://config.mail.163.com/settings/imap/index.jsp?uid=YOUR_EMAIL_NAME@126.com
Replace YOUR_EMAIL_NAME by yourself.
把里面YOUR_EMAIL_NAME替换掉，然后登录，手机验证，就可以了。
