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，我使用的是 PHPMailer。这是我在 example.com/contactus 网站上使用的代码段：

        $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-8\r\n';
        $mail->WordWrap = 70;

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

该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作为用户名和密码进行身份验证时，不会发送消息。错误是：

我不知道为什么它可以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，但是哪个？

好吧，我不知道为什么它不起作用。最后，我更改为 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。
