Not able to send email using PHP - php

Question

I have a simple PHP form with few fields and form details are sent using following code mentioned below..
Even thought i get "Thank you. Your messsage has been received." message but message never comes through.
I tried changed $use_smtp = '0'; still doesn't work
<?php
include('SMTPClass.php');
$use_smtp = '1';
$emailto = 'info#domain.com';
// retrieve from parameters
$emailfrom = isset($_POST["email"]) ? $_POST["email"] : "";
$nocomment = isset($_POST["nocomment"]) ? $_POST["nocomment"] : "";
$subject = 'Email from Website';
$message = '';
$response = 'Thank you for your message. I will be in contact shortly.';
$response_fail = 'There was an error verifying your details.';
// Honeypot captcha
if($nocomment == "") {
$params = $_POST;
foreach ( $params as $key=>$value ){
if(!($key == 'ip' || $key == 'emailsubject' || $key == 'url' || $key == 'emailto' || $key == 'nocomment' || $key == 'v_error' || $key == 'v_email')){
$key = ucwords(str_replace("-", " ", $key));
if ( gettype( $value ) == "array" ){
$message .= "$key: \n";
foreach ( $value as $two_dim_value )
$message .= "...$two_dim_value<br>";
}else {
$message .= $value != '' ? "$key: $value\n" : '';
}
}
}
$response = sendEmail($subject, $message, $emailto, $emailfrom);
} else {
$response = $response_fail;
}
echo $response;
// Run server-side validation
function sendEmail($subject, $content, $emailto, $emailfrom) {
$from = $emailfrom;
$response_sent = 'Thank you. Your messsage has been received.';
$response_error = 'Error. Please try again.';
$subject = filter($subject);
$url = "Origin Page: ".$_SERVER['HTTP_REFERER'];
$ip = "IP Address: ".$_SERVER["REMOTE_ADDR"];
$message = $content."\n$ip\r\n$url";
// Validate return email & inform admin
$emailto = filter($emailto);
// Setup final message
$body = wordwrap($message);
if($use_smtp == '1'){
$SmtpServer = 'smtp.office365.com';
$SmtpPort = '587';
$SmtpUser = 'no-reply#domain.com';
$SmtpPass = 'password';
$to = $emailto;
$SMTPMail = new SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body);
$SMTPChat = $SMTPMail->SendMail();
$response = $SMTPChat ? $response_sent : $response_error;
} else {
// Create header
$headers = "From: $from\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/plain; charset=utf-8\r\n";
$headers .= "Content-Transfer-Encoding: quoted-printable\r\n";
// Send email
$mail_sent = #mail($emailto, $subject, $body, $headers);
$response = $mail_sent ? $response_sent : $response_error;
}
return $response;
}
// Remove any un-safe values to prevent email injection
function filter($value) {
$pattern = array("/\n/", "/\r/", "/content-type:/i", "/to:/i", "/from:/i", "/cc:/i");
$value = preg_replace($pattern, "", $value);
return $value;
}
exit;
?>

This example shows settings to use when sending via Google's Gmail servers.
SMTP needs accurate times, and the PHP time zone MUST be set
This should be done in your php.ini, but this is how to do it if you don't have access to that
