gmail - header 中的 List-Unsubscribe 可防止电子邮件发送到 Gmail

Question

我正在使用 phpmailer 发送电子邮件。

当我添加 list-unsubscribe 时，电子邮件会发送到除 gmail 之外的所有帐户。它只是被丢弃，不会进入垃圾邮件，只是永远不会到达 gmail 帐户。当我删除 list-unsubscribe 时，它​​成功发送到 gmail 帐户。

这是我正在使用的列表取消订阅:

List-Unsubscribe:<http://keepity.com>,<mailto:admin@keepity.com>

这是它在 phpmailer 中的调用方式:

$mail->AddCustomHeader("List-Unsubscribe:<http://keepity.com>,<mailto:admin@keepity.com>");

这是调用 phpmailer 的完整函数。如果我注释掉 list-unsubscribe 则邮件会发送到 gmail 帐户，否则它永远不会到达。有谁知道为什么不发货？

static function phpmailer_sendmail($mail,$from,$fromAlias,$to,$replyTo,$replyToAlias,$subject,$html,$text) {

    require_once (JPATH_COMPONENT.DS.'PHPMailer-master/class.phpmailer.php');

    $mail = new PHPMailer(true); // by setting TRUE you enable exceptions
    $mail->IsSMTP(true); // SMTP

    $mail->SMTPAuth   = true;  // SMTP authentication
    $mail->Mailer = "smtp";

    $mail->Host= "xyz"; // Amazon SES
    $mail->Port = 465;  // SMTP Port
    $mail->Username = "xyz";  // SMTP  Username
    $mail->Password = "xyz";  // SMTP Password

    $mail->ClearAllRecipients(); 
    $mail->ClearAddresses();
    $mail->ClearCCs();
    $mail->ClearBCCs();
    $mail->ClearReplyTos();
    $mail->ClearAttachments();
    $mail->ClearCustomHeaders();
    $mail->SetFrom($from, $fromAlias);
    $mail->AddReplyTo($replyTo,$replyToAlias);
    $mail->Subject = $subject;
    $mail->IsHTML(true);  
    $mail->Body    = $html;
    $mail->AltBody = $text;
    $address = $to;
    $addressAlias = $to;
    $mail->AddAddress($address, $addressAlias);
    $mail->AddCustomHeader("List-Unsubscribe:<http://keepity.com>,<mailto:admin@keepity.com>"); 
    $mail->Send();



}

Answer 1

函数 addCustomHeader 有 2 个参数
并且 unscribe 值格式应该是

  <email_to_unscribe@email.com>, <http://url_to_unscribe.com>

这是一个如何调用它的示例:

  $mail->addCustomHeader("List-Unsubscribe",'<admin@keepity.com>, <http://keepity.com/?email='.$address.'>');
