Mail attachment download

Hi,
I have a php script which I use to download an email attachment from my inbox to a folder on my site.
When the email is sent direct from the server that creates the .csv report, the script recognizes there is an email, but does not download the email attachment. If I have that email sent to my email (outlook exchange) and then I forward it to my site, the script works - sees the email and downloads the attachment to the specified folder.
I cant work this out. Any clues?

I don't think it is an issue with the script as I use pretty much the same code for the same purpose in other areas of the site, I feel its to do with the attachment being created in the first place. Unfortunately, I can do much with the creation of the csv file, I can only change it to an excel file of a PDF.

Here is the script

set_time_limit(3000);

$hostname = '{nysite.com:993/imap/ssl}INBOX';
$username = 'files@mysite.com';
$password = 'password';
$saveloc = 'DataFiles/';
$backUpsaveloc = 'DataFilesBackup/';



sleep(3);

    if($emails) {

    $count = 1;
    rsort($emails);
   
    foreach($emails as $email_number)
        {
        $overview = imap_fetch_overview($inbox,$email_number,0);
        $message = imap_fetchbody($inbox,$email_number,2);
        $structure = imap_fetchstructure($inbox, $email_number);
        $attachments = array();
        if(isset($structure->parts) && count($structure->parts))
            {

PHP:

 

It seems to me that the script on your server, which is creating the attachment is not doing its work as expected. Missing some headers etc while creating email.
This is why this download script is not parsing the email correctly, missing the attachment.

When you forward it to outlook and resend, then outlook is fixing the error, and script fetches the download.

 

Hi,
Yes that is also my suspicion. Unfortunately, I have no way of modifying what get sent, its the cards I'm dealt.
I guess I need to keep looking for a script that will read the attachment. There has to be a way, email clients can read the emails.
