How to disable error messages in PHPMailer?

I know this thread is old and already answered but I stumbled here because I had the same problem but ending up solving it differently so I thought I'd share. NOTE: I'm using PHPMailer v5.1.

When you instantiate the PHPMailer class, it takes one optional argument, $exceptions. That tells PHPMailer if it should throw exceptions if it encounters any. It defaults to false which means it does not throw any exceptions, just echoes its messages out. However, if you call it like

  $mail = new PHPMailer(true);

you will tell it to throw exceptions. You can then catch those exceptions and deal with them however you choose. To me, that is much cleaner and more elegant than messing with the source code or disabling the error reporting.

This is the way PHPMailer wants you to do it; does not involve editing the original class file.

$mail->SMTPDebug = false;
$mail->do_debug = 0;

This is not probably the best solution, but it works.

In your phpmailer library folder open "class.phpmailer.php",

find

public function Send()

inside it comment the line

echo $e->getMessage()."\n";
