Настройте Citadel для отправки электронной почты с помощью smtp

Извините за глупый вопрос, но я мало знаю о серверах. Так терпи меня!

Я настроил Citadel, как указано в документации linode, и могу войти в систему, используя интерфейс для доступа к citadel. Я могу отправлять электронные письма, используя это. Как я могу настроить smtp и использовать его в качестве почтового сервиса для отправки писем из laravel, который является фреймворком php ?. Любая помощь будет оценена по достоинству.

Я настроил его как

Enter 0.0.0.0 for listen address
Select Internal for authentication method
Specify your admin <username>
Enter an admin <password>
Select Internal for web server integration
Enter 80 for Webcit HTTP port
Enter 443 for the Webcit HTTPS port (or enter -1 to disable it)
Select your desired language

После этого я ввел имя почты в / etc / mailname так как

mail.domain.com

и я могу получить доступ к adn sendmail, используя https://mail.domain.com

Мой файл laravel mail.php 'driver' => 'smtp',
