在 java 程序中访问 GoDaddy 电子邮件时出错
Error while accessing GoDaddy emails in java program
我正在尝试将我的 GoDaddy 邮箱中的邮件读入我的 java 程序，但我遇到错误 PKIX 路径构建失败 。我尝试了 link 上显示的解决方案："PKIX path building failed" and "unable to find valid certification path to requested target"。但仍然是错误 persists.Is 我应该在我的 java 代码中包含任何内容。

smtp.properties.txt 在这里：
mail.smtp.host=smtpout.secureserver.net
mail.smtp.socketFactory.port=465
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.auth=true
mail.smtp.port=465
Get rid of the socket factory settings, you don't need them.
就此而言，我没有看到您在应用程序中的任何地方使用属性文件，甚至没有对 smtp 进行任何操作，因此您可以删除该文件。
然后关注these instructions in the JavaMail FAQ.
如果你不知道如何安装证书，设置这个属性忽略证书（注意这是一个安全风险）：
