PHP:解析由Amazon SES保存到S3的文件中的邮件

我使用Amazon SES的Rule Set将发送到我的域的所有邮件定向到SES Bucket。我现在试图以编程方式读取这些文件，但无法弄清楚如何做到这一点。我研究了这个主题，发现了PHP的Mailparse函数。我的代码是:

    $filnename = '/Users/R00tUser/Downloads/u38sf1l0jcd4s1tifl59a10psc16i7nfoaq2c64';
    $resource = mailparse_msg_parse_file($filename);
    $parts = mailparse_msg_get_structure($resource);
    var_dump($parts);
    $text = mailparse_msg_extract_whole_part_file($resource, $filename);
    var_dump($text);

var_dump的输出都是bool(false)。由于这些方法的文档几乎不存在，我不知道哪里出了问题。能否有人请纠正我的代码中的错误，或者请建议一个更好的方法来做我想做的事情。

我试图解析的文件内容:
