Azima:

I'm using phpMailer to send Emails. Email recipients are passed as an array, and are added by looping through this array. Example:

public static function mailTo($recipients)
{
    $f3 = \Base::instance();
    $user = AclHelper::getCurrentUser();
    $template= new \Template;
    $mailBody= $template->render('leave/emailTemp.html');

    // When true, PHPMailer returns exceptions
    $mail = new PHPMailer(true);
    try {
        $mail->isSMTP();                                      // Set mailer to use SMTP
        $mail->isHTML(true);

        $mail->addAddress($user['email']);
        $mail->addAddress("[email protected]");
        $mail->addAddress("[email protected]");

        foreach($recipients as $recipient){
            $mail->addAddress($recipient);
        }

        $mail->SMTPAuth = true; // authentication enabled
        $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
        $mail->Host = "smtp.gmail.com";
        $mail->Port = 465; // or 587
        $mail->Username = "[email protected]";
        $mail->Password = "abcd";

        $mail->setFrom($user['email']);

        $userFullName = trim(ucfirst($user['firstname'])) . " " . trim(ucfirst($user['lastname']));
        $mail->FromName = $userFullName;
        $mail->Body =  $f3->get('message');
        $mail->Body .="
". $mailBody;
        $mail->Subject = 'Updates on leave date applied';

        $mailStatus = (boolean)$mail->send();

        if ($mailStatus === true) {
            return $mail;
        }
    } catch (phpmailerException $e) {
        $response = array(
            'status'=>'error',
            'message'=>'Got some error while sending emails',
            'exceptions'=>$e->getMessage()
        );
        return $response;

    } catch (Exception $e) {
        $response = array(
            'status'=>'error',
            'message'=>'Got some error while sending emails',
            'exceptions'=>$e->getMessage()
        );

        return $response;
    }
}

Emails are being sent to and received by recipients whose addresses are set statically. eg.

$mail->addAddress("[email protected]");
    $mail->addAddress("[email protected]");

The problem is that there might exist some "invalid" emails among these recipients. For eg. "[email protected]".

It seems that whenever phpMailer encounters these type of addresses, it doesn't send emails to any other "valid" addresses as well.

How can I make PhpMailer work such that "valid" emails receive emails like in Gmail.

Any help is very much appreciated. Thanks.
