我们安装了 SPF、DKIM 和 DMARC 记录以确保电子邮件安全/可验证性。
通过控制台或邮件客户端（例如 Outlook 或 Mac 的 Mail）发送时，它会进行全面处理，并且所有三个都会通过。
通过 Zend Framework 1.12 的 SendMail 函数发送时失败（php）。
我们是否错过了某个配置，导致 php 电子邮件也签名了？我们要查看哪个文件？还是必须有不同的安装/附加组件？
我们在 Cent OS 6 上使用 OpenDKIM 和 Postfix

这是我从 Port25 电子邮件检查器获得的结果。除了 zend 时缺少 DKIM 外，其他都一样。

答案1
通过控制台或邮件客户端（例如 Outlook 或 Mac 的 Mail）发送时，它会进行全面处理，并且所有三个都会通过。
此行为是预期行为，因为您将此配置放在main.cf
smtpd_milters = inet:localhost:8891
通过 Zend Framework 1.12 的 SendMail 函数发送时失败（php）。
此行为也是预料之中的，因为您将此配置放在main.cf
non_smtpd_milters =
解释
默认情况下，OpenDKIM 与 postfix 结合使用，米尔特. 启用/禁用 milter 应用程序由smtpd_milters和non_smtpd_milters参数。对于通过 smtpd 发送邮件的应用程序，对应的参数为smtpd_milters，对于 sendmail ，对应的参数为non_smtpd_milters
解决方案
non_smtpd_milters =用。。。来代替
non_smtpd_milters = inet:localhost:8891
