推荐答案
它与 PHP 代码无关，但要确保电子邮件是从托管在服务器上的域发送的.这意味着使用您的 gmail 地址通过 PHP 发送将是一个坏主意.每封离开服务器的电子邮件都需要签名并需要有 SPF 记录
It has nothing to do with the PHP code but make sure that the email are being sent from a domain that is hosted on the server. That means it would be a bad idea to use your gmail address for sending though PHP. Every email that leaves the server needs to be signed and needs to have SPF records
这通常是因为在 DNS 中没有设置正确的 SPF 记录.这可以轻松完成，具体取决于您使用的软件.如果您使用 cPanel，那么这几乎是一个两步过程.
This is usually because in the DNS a correct SPF record has not been setup. This can be easily done depending on the software you use. If you use cPanel then this is pretty much a two step process.
