这是我的PHPmailer代码：

$mail = new PHPMailer();
$mail->Issmtp();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl'; 
$mail->Host = "smtp.gmail.com";
$mail->Port = 587;
$mail->IsHTML(true);
$mail->Username = "testnoreply@gmail.COM";
$mail->Password = "test";
$mail->SetFrom("testnoreply@gmail.com");
$mail->Subject = "Membership expire notice";
$mail->Body = "Dear ICONIS member your membership is going to expire please renew IT";
$mail->AddAddress($em);

if (!$mail->Send()) {
  echo "Mailer Error: " .$mail->ErrorInfo;
} else {
  echo "Mail has been sent";
}
