对自建域名发信报x509错误

[Ariczh]

请完整读完README再提问! / Before asking questions, please read the README !

请说明问题 / Describe the bug A clear and concise description of what the bug is. 我的部署环境在内网，域名全都是只存在于内网DNS上的虚假域名，发送服务器（Pmail）和收件方（非pmail）都是如此。当我对真实存在的邮件域名发信（如xxx@qq.com）时，投递正常，对内网虚假域名发信时会报错： 邮件投递失败tls: failed to verify certificate: x509: certificate is not valid for any names, but wanted to match any.kap 这里any.kap是虚假域名，它仅存在于我的内网DNS上，在DNS上设置了对应的A记录和MX记录。 是否可以关闭相关的tls验证？

如何复现 / To Reproduce Steps to reproduce the behavior: 对不存在于公网的域名发信即可复现。

你预期的行为 / Expected behavior A clear and concise description of what you expected to happen. 正常发送邮件

或许是传输过程的starttls导致的问题？是否可以关闭starttls？

目前针对localhost域名没有校验证书有效性。要么你自己编译一个版本，把你的域名加到这里，要么把你自签证书加到双方系统的可信列表里面吧

我来安装自签证书试试看
