我有这个错误

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Authentication required

推荐答案

我测试了整个我自己的IDE中的代码和此问题的结果是用户名/密码匹配错误。 确保您使用的是服务器上有效用户名的正确密码。 可能的问题：你问的是关于Gmail的问题，但是你正在使用Yahoo smtp服务器。你确定你正在使用雅虎服务器凭据的正确设置，或者你错误地写了雅虎的主机地址吗？ I have tested this entire code in my own IDE and the result for this problem was the username/password match error. Make sure that you're using the correct password for the valid username on the server. Possible issue: You're asking a question about Gmail, but you're using the Yahoo smtp server. Are you sure you're using the correct settings for credentials for the Yahoo server, or did you mistakenly wrote that Yahoo smpt host address?

首先 string smtpAddress =smtp.gmail; 秒 查看您的凭证，帐户的用户名和密码 first string smtpAddress = "smtp.gmail"; second check ur credentials , username and password of ur account
