I want to send an email and I am using the code below. It always works on my test server and my production server which are both IIS on Windows. It sometimes works the client's server. Once or twice in ten it sends. The client's server is running Apache on Linux. Could this be significant? Any other ideas why it would only work intermitently?
I have included everything except input validation (way too much code - not needed for testing) and the three images. If anyone is kind enough to test this for me then the images can be found here:
http://www.slymedesign.co.uk/images/top.png
http://www.slymedesign.co.uk/images/welcome-top.jpg
http://www.slymedesign.co.uk/images/welcome-bottom.jpg
Although, to be honest, I don't think that the email is the problem. I get similar results if I strip the email message right down to simple 'Hello World' stuff.
<?php
$ready_to_send = false;
$send_status = '';
if (isset($_POST['submit'])) {
$to = $_POST['email'];
$ready_to_send = true;
}
if ($ready_to_send) {
$top_png = chunk_split(base64_encode(file_get_contents('top.png')));
$welcome_top_jpg = chunk_split(base64_encode(file_get_contents('welcome-top.jpg')));
$welcome_bottom_jpg = chunk_split(base64_encode(file_get_contents('welcome-bottom.jpg')));
$subject = 'Multipart Email Test';
$headers = "From: $to\r\nReply-To: $to";
$headers .= "\r\nContent-Type: multipart/related; type=\"multipart/alternative\"; boundary=\"----=_NextPart_000_0070_01CAFD85.CD836AE0\"";
ob_start();
?>
