我整理了一个运行nginx，PHP和MSMTP的Docker映像。 我可以交互方式从容器中发送电子邮件，但是当我尝试从PHP脚本发送电子邮件时，它会失败。 我正在努力弄清楚为什么我无法正确地将日志记录到正确的管道上，但这是一个单独的问题。 我真的只需要发送电子邮件，这样我就可以关闭这个小型迷你项目。 任何帮助都得到了极大的赞赏。 另外，PHP工作正常，没有错误的说法。 dockerfile

我很清楚日志可能会有所帮助，但是说实话我整天都在试图从我的形象中获得适当的日志，但我一直在打破任何东西。

我弄清楚了。 邮件函数在传递了3个以上的参数之后非常井井有条。它应该接受更多（例如电子邮件标题），但似乎不起作用。
