PHPMailer not always delivering

[cinder09]

Hey, I'm having problems with the php mailer.

I'm having a little webapp, where the user uploads images. These images then are embeded to an email and (together with a pdf) put inside a zip and attached to the email.
This email then is sent to the user and the host of the site.

The email is sent automatically in two ways: one way the user klicks a link where the php-script is fired.
The second way is via paypal - after purchase the user is redirected to the php-page which automatically sends the email.
BUT, the emails aren't delivered all the time.
This is a huge problem especially after the paypal-purchase, since the email is essential for further steps and the customer already paid.

When I test it from my computer, it mostly works (is there any connection since it's the same computer...I don't know)

Here's the code

[...]generate pdf, zip file, set content for email and so on[...]

$mail = new PHPMailer();

$mail->CharSet = 'utf-8';
$mail->From = '[email protected]';    
$mail->FromName = "Testname";  
$mail->AddReplyTo("[email protected]", "Testname"); 

$mail->addAddress('[email protected]', 'Test Name');
$mail->addAddress($_SESSION["CustomerMail"], $_SESSION["CustomerName"]);

$mail->Body = $content;

$mail->WordWrap = 50;    
$mail->IsHTML(true);

$mail->Subject = "EMAIL SUBJECT";


/*———————————————————————————*/
/*——————— ADD IMAGES ————————*/
/*———————————————————————————*/

for($i = 0; $i< $_SESSION["productCount"];$i++)
{
    $currImg = base64_encode(file_get_contents($imagenames[$i]));
    $src = 'data: '.mime_content_type($imagenames[$i]).';base64,'.$currImg;

    $mail->AddEmbeddedImage($imagenames[$i], 'imgname'.$i, 'imgname'.$i);
}


$mail->AddAttachment("../FOLDER/".$_SESSION['foldername']."/zipname.zip");

if(!$mail->Send())
{
   echo "Die Email konnte nicht versendet werden, wenden Sie sich bitte an <a href='mailto:[email protected]'>[email protected]</a>";
   echo "Mailer Fehler: " . $mail->ErrorInfo;
   exit;
}
else
{

[...]Delete session,zip, files, and so on[...]

I really hope you can help me

Why are you doing all that base64_encode etc with the images? You don't seem to be using $src anywhere. Are you sure that $content contains all the matching identifiers you're using in addEmbeddImage? If it's not meant to match, you should be using the simpler addAttachment instead.

You don't need to set WordWrap - that will be a leftover from an old example script.

As far as delivery goes, you're sending via your local mail server, so you need to look in your mail server log to see what is happening as that's outside PHPMailer's control.

for($i = 0; $i< $_SESSION["productCount"];$i++)
{
    $currImg = base64_encode(file_get_contents($imagenames[$i]));
    $src = 'data: '.mime_content_type($imagenames[$i]).';base64,'.$currImg;


    $content .=
    '<tr>
    <td><table width="600" border="0" cellpadding="0" cellspacing="0">
    <tr>
    <td colspan="3" style="font-size:18px; font-weight: normal; color:#070000; text-transform: uppercase;">image '.($i+1).'</td>
    </tr>
    <tr>
    <td colspan="3">&nbsp;</td>
    </tr>
    <tr>
    <td width="146" rowspan="4" valign="top" style="padding:0"><img src="cid:imgname'.$i.'" alt="imgname'.$i.'" width="146"></td>
    <td width="40">&nbsp;</td>
    <td style="color:#000; font-size:15px; height: 146px;">'
    </td>
    </tr>
    <tr>
    <td width="40">&nbsp;</td>
    <td>&nbsp;</td>
    </tr>
    <tr>
    <td width="40">&nbsp;</td>
    <td>&nbsp;</td>
    </tr>
    <tr>
    <td valign="top">&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    </tr>
    </table></td>
    </tr>';

}

I'm embeding the images like so. It seems like I'm redeclaring the $src inside the loop.
Anyway the images are embeded correctly when the email is delivered

I guess using smtp won't solve the issue.
The emails are pretty big too.

OK, so it looks like you can get rid of $currImg and $src then.

So what does your mail server say?

[cinder09]

sadly I don't have access to a mail log, but I'll try it with smtp, maybe this will solve the problem
