So I know this is a year late, but I had the same problem and figured out how to download the attachments. The files in the post are in stored in the environmental variable $_FILES. The information for each file will look something like:

Array
(
    [attachment-1] => Array
        (
            [name] => ATextFile.txt
            [type] => text/plain
            [tmp_name] => /tmp/php8zhmlU
            [error] => 0
            [size] => 70144
        )
)

The path to the file is stored in tmp_name, so in this case, /tmp/php8zhmlU is the full path to the file. move_uploaded_file will overwrite any existing files! To download all the attachments from the POST I wrote a function:

function download_attachments($pathToDownloadDirectory)
{
    foreach($_FILES as $file)
    {
        if($file['error'] == "0")
        {
            if(!(move_uploaded_file($file['tmp_name'], $pathToDownloadDirectory . $file['name'])))
            {
                return 0;
            }
        }
        else
        {
            return 0;
        }    
    }
    return 1;
}

download_attachments("/Full/Path/To/Some/Dir/");

Documentation for this top can be found here.

use store action from route session in order to obtain information about your email. (retrieving stored message
json_decode "attachments" property in order to obtain information about your attachments
get api key and use php library in order to use get api.

if you json decoded list of attachments is $files, you can do

$mgClient = new Mailgun('yourApiKey');

foreach ($files as $file){
    file_put_contents($file->name,$mgClient->get($file->url)->http_response_body);    
}

to download every attachment
