如何修复向不同的人发送不同的电子邮件 PHPMailer

Question

我将向不同的人发送不同的电子邮件。第一封邮件发送正常，但第二封邮件等待 180 秒，然后开始发送。我找不到任何默认设置。一旦发送了一封电子邮件，其他人就会去 POOLING 并失败。

我有不同的身体和不同的主题。

代码 1：

    sendEmail(false, $email, $message, $subject, $dep_type);
    sendEmail(true, $email, $message_client, $subject_client);

发送电子邮件功能：

function sendEmail($client, $email, $message, $subject, $dep_type = null)
{
    $from_mail = 'hello@example.com';

    $mail = new PHPMailer(true);

    $mail->IsSMTP();
    $mail->Host = 'email-smtp.us-east-1.amazonaws.com';

    $mail->SMTPAuth = true;
    $mail->Username = 'username';
    $mail->Password = 'password';
    $mail->From = $from_mail;
    $mail->FromName = "SenderName";
    if ($client) {
        $mail->addAddress($email);
    } else {
        $mail->addAddress('welcome@example.com');
    }
    $mail->addReplyTo($from_mail, 'name');
    $mail->isHTML(true);
    $mail->Subject = $subject;
    $mail->Body = $message;
    $mail->send();

}

Amazon EC2 throttles traffic on port 25 of all EC2 instances by default, but you can request for this throttle to be removed.
