Also, check that SMTP is working: https://stackoverflow.com/questions/11988454/how-to-check-if-smtp-is-working-from-commandline-linux — Fergal Andrews, Sep 20 '18 at 15:37
I could be wrong but your mail host setting ($mail->Host = 'vps203527.vps.ovh.ca'; ) looks a bit strange. The username also ($mail->Username = 'admin@ .com') — Fergal Andrews, Sep 20 '18 at 15:58

You are facing the issue because you have entered incorrect host value in your PHP script. Please enter your SMTP servers name in the host field [$mail->Host = 'vps203527.vps.ovh.ca';]. It should be like mail.yourdomainname.com

I also faced the same error and I fixed it by using the following code.

Following is the sample code to send email from your PHP script with SMTP authentication:

<?php
require("class.phpmailer.php");

$mail = new PHPMailer();

$mail->IsSMTP();                                // send via SMTP
$mail->Host     = "smtp.domain.com"; // SMTP servers
$mail->SMTPAuth = true;     // turn on SMTP authentication
$mail->Username = "email@domain.com";   // SMTP username
$mail->Password = "password"; // SMTP password

$mail->From     = "email@domain.com";
$mail->FromName = "Name";
$mail->AddAddress("Recipient@emailaddress.com","Name");
$mail->AddReplyTo("yourname@domain.com","Your Name");

$mail->WordWrap = 50;                 // set word wrap

$mail->IsHTML(true);                               // send as HTML

$mail->Subject  =  "Here is the subject";
$mail->Body     =  "This is the <b>HTML body</b>";
$mail->AltBody  =  "This is the text-only body";

if(!$mail->Send())
{
   echo "Message was not sent <p>";
   echo "Mailer Error: " . $mail->ErrorInfo;
   exit;
}

echo "Message has been sent";

?>

Please make sure that you make the changes in the above script as necessary. 

Note: You should always verify the email address before sending an email campaign.

Please let me know if you face any issue. I will try to fix it.

Thank you!
