使用 PHPMailer 发送电子邮件时，我的 Gmail 邮件警告

Question

我需要有关使用 phpmailer 发送邮件的疑难解答方面的帮助。 我尝试使用 PHPmailer v6 发送邮件，一切正常，但是当我在 gmail 上收到消息时，我收到 RED MARK 警告消息：

This message appears dangerous
This message may contain unsafe content as many people have identified similar messages as phishing scams. So avoid clicking on links, downloading attachments, or responding with any personal information.

我真的不知道这条消息的原因，这是我在脚本中使用的代码：

$link ="<a href='".$setting['site_url']."?v=".$rand."'>".$setting['site_url']."?v=".$rand."</a>";
$mes='Hello,<br><br> Thank you for registering at '.$setting['faucet_name'].'. However, before you getting running on the site, you\'ve to confirm your email address.<br> Click here:  <b>'.$link.'</b><br> to confirm your account, or copy the link below directly to confirm your email address.<br><br> Regards,<br> '.$setting['faucet_name'].'<br><br><small>If you didn\'t apply for an account, please ignore this email and you won\'t be bugged again.</small>';

    $from='no-reply@'.$_SERVER['HTTP_HOST'];
    $mail = new PHPMailer();

    //Recipients
    $mail->setFrom($from, $setting['faucet_name']);
    $mail->addAddress($email, $username);                 
    // Content
    $mail->isHTML(true);                                 
    $mail->Subject = 'Confirm your account at '.$setting['faucet_name'];
    $mail->Body    = $mes;
    $mail->AltBody = 'please use HTML viewer to see the message';

    if($mail->send()){
    $stmt= $db->prepare("INSERT INTO verify_user(username,email,password,ref,verify_key,created)VALUES(?,?,?,?,?,?) ");
    $stmt->bind_param("sssssi",$username,$email,$password,$ref,$rand,$time);
    $stmt->execute();
    echo json_encode(array('success' =>'Message sent!'));
} else {
    echo json_encode(array('success' => "Message could not be sent."));
}

虽然我不确定，但我想说问题不在您的代码中。

这很可能来自邮件本身的内容，正如 Gmail 所说的那样。它的算法根据一些标准估计您的电子邮件类似于通常由网络钓鱼者发送的许多电子邮件。因此，它会在您的收件箱中警告您这封邮件。
