Error in sending email using phpmailer - Relaying disallowed SMTP Error: data not accepted

Question

I am trying to send email using phpmailer, but the following code fails to send email with this error:

SMTP ERROR: DATA END command failed: 553 Relaying disallowed SMTP Error: data not accepted. Mailer Error: SMTP Error: data not accepted.

Code is below:

<?php
require 'phpmailer/PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->isSMTP();
$mail->CharSet = 'UTF-8';
                                      // Set mailer to use SMTP
$mail->Host = 'smtp.zoho.com';  // Specify main and backup server
$mail->SMTPDebug  = 1;
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '[email protected]';                            // SMTP username
$mail->Password = '846Support.x.1';                           // SMTP password
$mail->SMTPSecure = 'ssl';   
$mail->Port = 465;                         // Enable encryption, 'ssl' also accepted

$mail->From = $_POST['email'];
$mail->FromName = $_POST['name'];
$mail->addAddress('[email protected]');  // Add a recipient
$mail->addReplyTo($_POST['email'], $_POST['name']);

$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$mail->isHTML(true);                                  // Set email format to HTML

$body = $_POST['message'];
$body = wordwrap($body, 70, "\r\n");
$body = $body . "\r\n" . "Phone: " .$_POST['phone'];

$mail->Subject = 'Contact Form';
$mail->Body    = $body;

if(!$mail->send()) {
    echo 'Mailer Error: ' . $mail->ErrorInfo;
    exit();
}
else
{
    echo 'success';
}
?>

the smtp message says that your mailhost don't allow relaying mails. so you need to ask your provider to allow relaying for your server — sHentschel
I'm not finding any problem with your code. have you tried with other smtp(gmail). $body = wordwrap($body, 70, "\r\n"); that will wrap your email body. kindly check with your mailhost provider and try with short html body — sas

I guess Zoho SMTP server doesn't accept sending mail with from e-mail diferent of smtp login mail.. I changed and it has passed imediatelly.
