PHP mail script, email is not sent

Question

I am trying to send mail through a simple PHP script mail. I checked the code many times, the page goes to the "Thankyou_page" page, as if the mail was sent, but I have not yet received the letter. Any ideas why this is not working?

<?php /* This first bit sets the email address that you want the form to be submitted to. You will need to change this value to a valid email address that you can access. */ $webmaster_email = " [e-mail] "; $subject = "Contact Us"; /* This bit sets the URLs of the supporting pages. If you change the names of any of the pages, you will need to change the values here. */ $feedback_page = "feedback_form.html"; $error_page = "error_message.html"; $thankyou_page = "thank_you.html"; /* This next bit loads the form field data into variables. If you add a form field, you will need to add it here. */ $email_address = $_REQUEST['email_address'] ; $comments = $_REQUEST['comments'] ; /* The following function checks for email injection. Specifically, it checks for carriage returns - typically used by spammers to inject a CC list. */ function isInjected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if(preg_match($inject,$str)) { return true; } else { return false; } } // If the user tries to access this script directly, redirect them to the feedback form, if (!isset($_REQUEST['email_address'])) { header( "Location: $feedback_page" ); } // If the form fields are empty, redirect to the error page. elseif (empty($email_address) || empty($comments)){ header( "Location: $error_page" ); } // If email injection is detected, redirect to the error page. elseif ( isInjected($email_address) ) { header( "Location: $error_page" ); } // If we passed all previous tests, send the email then redirect to the thank you page. else { mail( $webmaster_email, $subject, $comments, "From: " . $email_address); header( "Location: $thankyou_page" ); } ?> 

Answer 1

Use a well-written library like SwiftMailer or PHPMailer. Sending email using the mail function without a good PHP command is a killer.

PhpMailer vs SwiftMailer?

Answer 2

Did you specify the smtp node in the php.ini file? If so, is that right?

Also, turn off the header and print the output of the mail function to make sure this is happening. It would also be nice to include an error report in the php.ini file.

Is [e-mail] valid email?
