php form not sending info via email about 30% of time

[Dilmorier]

I'm getting a 'this message has no content' error about 30% of the time a visitor completes the form and cannot isolate the problem. The php for sending the email is below with addresses anonymized. Any ideas?I've tried to find an answer in the forums to no avail so far. Thanks for your help!\[code\]<?php $fromAddress = '[email protected]'; $subject = 'Resources - White Paper Download - '.$_POST['WhitePaper']; $message .= "\r\n"; foreach($_POST as $name => $value) { $message .= $name . ': ' . $value . "\r\n"; } $to = '[email protected]'; $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/plain; charset=UTF-8' . "\r\n"; $headers .= 'From: ' . $fromAddress . "\r\n" . 'Reply-To: ' . $fromAddress . "\r\n" . 'X-Mailer: PHP/' . phpversion(). "\r\n"; $headers .= 'Cc: [email protected], <[email protected]>' . "\r\n"; mail($to, $subject, $message, $headers); echo "mail sent";?>\[/code\]
