Ubuntu

從 PHP 腳本發送的郵件未顯示

  • March 24, 2020

我在兩個執行 Ubuntu 的 AWS EC2 實例上執行一個網站。我正在使用燈。以下 PHP 程式碼用於成功發送電子郵件，以警告可疑活動，但在 2020 年 1 月停止這樣做。

<?php
   // Function to email notification of suspicious entry
   function emailPossibleSQLInjectionNotification($ipAddress, $emailAddress, $field, $entry, $time)
   {
           $to = "otagoHarbour@gmail.com";
           $subject = "Suspicious activity";
           $message = "Dear Sir,\n\n" .
                   "The following invalid entry was entered for " . $field . ".\n\n" .
                   $field . ": " .  $entry . "\n" .
                   "Client IP address" . ": " .  $ipAddress . "\n" .
                   "Client email address" . ": " .  $emailAddress . "\n" .
                   "Time" . ": " .  $time . "\n\n" .
                   "Have a wonderful day!\nWeb Site Name.\n";
           $from = "websiteSiteName@websiteSiteName.com";
           $headers = "From:" . $from;
           mail($to,$subject,$message,$headers);
   }
?>

以下

以下

$ sudo netstat -ntlp | grep sendmail

返回

ISP 不會成為問題，因為我是從雲上的 AWS EC2 實例執行應用程序。

我注意到

df -i

返回

所以這不是 inode 的問題。

ps -e | grep sendmail

返回

 4320 ?        00:00:00 sendmail-mta

郵件只是沒有顯示，即使是垃圾郵件文件夾。

編輯：

我也試過

ubuntu@ip-10-0-1-76:~$ sendmail otagoharbour@gmail.com
Test
ubuntu@ip-10-0-1-76:~$

我的 gmail 帳戶中仍然沒有郵件顯示。

這是由於 AWS 所做的更改。我解決瞭如下問題。

  1. 按照此處所述安裝並設置 Postfix 。
  2. 編輯 AWS EC2 實例過濾器以允許埠 587 上的 SMTP。
  3. 編輯 /etc/postfix/main.cf 以包含 relayhost =$$ email-smtp.us-east-1.amazonaws.com $$:587.
  4. sudo 後綴重新載入
