我只是掛斷電話發送服務器電子郵件。我正在準備這樣的電子郵件發送代碼：$email_config = Array( 'charset' => 'utf-8', 'mailType' => 'html');$email = \Config\Services::email();$email->initialize($email_config);$email->setNewline("\r\n");$email->setCRLF("\r\n");$email->setFrom("[email protected]", "Sender name");$email->setTo("[email protected]");$email->setSubject("Test message");$email->setMessage("Hello");if ($email->send()) { echo "Email sent!";} else { echo $email->printDebugger(); return false;}它顯示此錯誤消息：Unable to send email using PHP mail(). Your server might not be configured to send mail using this method.Date: Thu, 4 Jun 2020 05:21:47 -0500From: "Sender name" <[email protected]>Return-Path: <[email protected]>Reply-To: <[email protected]>User-Agent: CodeIgniterX-Sender: [email protected]: CodeIgniterX-Priority: 3 (Normal)Message-ID: <[email protected]>Mime-Version: 1.0Content-Type: multipart/alternative; boundary="B_ALT_5ed8cb3ba9e702.65790334"=?UTF-8?Q?Test=20message?=This is a multi-part message in MIME format.Your email application may not support this format.--B_ALT_5ed8cb3ba9e702.65790334Content-Type: text/plain; charset=UTF-8Content-Transfer-Encoding: 8bitHello--B_ALT_5ed8cb3ba9e702.65790334Content-Type: text/html; charset=UTF-8Content-Transfer-Encoding: quoted-printableHello--B_ALT_5ed8cb3ba9e702.65790334--并在錯誤日志中給出錯誤：Email: sendWithMail throwed Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46' (this will throw an Error in a future version of PHP)我想提一下，國際擴展在服務器中啟用。我正在使用控制面板。它在 Codeigniter 3 上運行良好。郵件功能在我的服務器中使用 row 方法，如下所示：$to = '[email protected]';$subject = 'Test message';$message = 'Hello';$headers = 'From: [email protected]' . "\r\n" . 'Reply-To: [email protected]' . "\r\n" . 'X-Mailer: PHP/' . phpversion();mail($to, $subject, $message, $headers);請幫忙。提前致謝。

codeigniter 提供替代類型（Mail、Sendmail 和 SMTP）檢查您的 cpanel 外發電子郵件配置或要求您的提供商檢查 php 的 mail() 配置

您需要在您的服務器上設置 MTA（郵件傳輸代理）。
例如：Postfix 或 exim，在某些情況下 nullmailer 可以解決問題
可能您可以連接到提供商的 SMTP 中繼

我今天遇到了這個，很驚訝地看到圖書館開箱即用。似乎是 CI 的電子郵件庫中的一個問題：
/**
* Validate email for shell
*
* Applies stricter, shell-safe validation to email addresses.
* Introduced to prevent RCE via sendmail's -f option.
*
* @see https://github.com/codeigniter4/CodeIgniter/issues/4963
* @see https://gist.github.com/Zenexer/40d02da5e07f151adeaeeaa11af9ab36

* @param string $email

* @return boolean
*/
protected function validateEmailForShell(&$email)
{
if (function_exists('idn_to_ascii') && $atpos = strpos($email, '@'))
{
$email = static::substr($email, 0, ++$atpos)
. idn_to_ascii(static::substr($email, $atpos), 0, INTL_IDNA_VARIANT_UTS46);
}
return (filter_var($email, FILTER_VALIDATE_EMAIL) === $email && preg_match('#\A[a-z0-9._+-]+@[a-z0-9.-]{1,253}\z#i', $email));
}
我沒有時間研究這個方法的全部內容（已經浪費了幾個小時?。?，但能夠繞過它并成功發送電子郵件。創建App/Libraries/Email.php以覆蓋有問題的方法：
<?php namespace App\Libraries;
class Email extends \CodeIgniter\Email\Email{
protected function validateEmailForShell(&$email){
return TRUE;
}
}
然后讓服務返回你的子類App/Config/Services.php：
public static function email(bool $getShared=TRUE){
return $getShared ? static::getSharedInstance('email') : new \App\Libraries\Email();
}
