Could not send mail please check your php mail configuration

The classic "Could not send mail" error!

This error message typically occurs when PHP is unable to send an email using the mail() function or a PHP mail library like SwiftMailer or PHPMailer. Here are some common reasons and solutions to help you troubleshoot the issue:

  1. PHP mail configuration:
    • Check your PHP configuration file (php.ini) for the following settings:
      • sendmail_path: Make sure it's set to a valid path or a mail server (e.g., /usr/sbin/sendmail -t -i or smtp://your-smtp-server.com).
      • SMTP: Set the SMTP server and port (e.g., smtp.gmail.com and 587).
      • smtp_port: Set the SMTP port (e.g., 587).
    • Restart your web server or PHP-FPM service to apply changes.
  2. Mail server configuration:
    • Verify that your mail server is configured correctly:
      • Check your mail server's logs for errors or issues.
      • Ensure that your mail server is not blocking the connection or rejecting the email.
  3. Email address and authentication:
    • Verify that the email address and password are correct:
      • Check the email address and password for typos or incorrect formatting.
      • Ensure that the email address exists and is not blocked by the mail server.
  4. PHP mail function:
    • Check the PHP mail function being used:
      • Make sure you're using a valid mail function (e.g., mail(), SwiftMailer, or PHPMailer).
      • Verify that the mail function is configured correctly.
  5. Firewall and network issues:
    • Check your firewall and network settings:
      • Ensure that the mail server is not blocked by your firewall or network settings.
      • Verify that the mail server is reachable and responding to connections.
  6. PHP version and extensions:
    • Check your PHP version and extensions:
      • Ensure that you're running a supported PHP version (e.g., PHP 7.2 or later).
      • Verify that the necessary PHP extensions are installed and enabled (e.g., php-mail or php-swiftmailer).

To troubleshoot the issue, you can try the following:

  1. Enable PHP error reporting to get more detailed error messages.
  2. Use a mail testing tool like Mail Tester or Mailinator to test your mail configuration.
  3. Check your PHP error logs for any errors related to mail sending.
  4. Verify that your mail server is configured correctly and is not blocking the connection.
