我正在使用Google的邮件服务器发送电子邮件。对于电子邮件发送，我正在使用PHPMailer。这是我在 example.com/contactus 网站上使用的代码片段：
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 2;
$mail->SMTPAuth = true; // enable SMTP authentication
$mail-> Host = 'ssl://smtp.gmail.com';
$mail->Port = 465; // set the SMTP port for the GMAIL server
$mail->Username = "myprivateaddress@gmail.com"; // GMAIL username
$mail->Password = "myprivatepassword"; // GMAIL password
$mail->SetFrom($form_email, $form_username);
$mail->AddAddress("support@example.com", "Example Support");
$mail->AddReplyTo($form_email, $form_username);
$mail->Subject = $subject2;
$mail->Body = $message2;
$mail->CharSet = 'UTF-8';
$mail->Encoding = '8bit';
$mail->ContentType = 'text/html; charset=utf-8rn';
$mail->WordWrap = 70;
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
代码向我发送一封电子邮件（support@example.com），其标题为：
from: user1 <myprivateaddress@gmail.com>
reply-to: user1 <user1@gmail.com> (this is $form_email)
to: Example Support <support@example.com>
问题是当我使用不同的地址进行身份验证作为用户名和密码时，不会发送消息。错误是：

我不知道为什么它与我每天使用的私人Gmail帐户一起使用，为什么不能与我拥有的其他Gmail帐户一起使用。它应该是gmail中的一个设置，但哪一个呢？
好吧，我找不到为什么它不起作用。最后，我改成了SendGrid。他们提供了一个简单的API，我用我的基本技能在一个小时内设置了电子邮件发送。
