Правильная реализация сертификата SSL на apache2 server?

Файл /etc/apache2/sites-available/maindomain.com.conf

Вот содержимое файла maindomain.com.conf внутри каталога доступных сайтов:

    <VirtualHost *:80>
            # The ServerName directive sets the request scheme, hostname and port that
            # the server uses to identify itself. This is used when creating
            # redirection URLs. In the context of virtual hosts, the ServerName
            # specifies what hostname must appear in the request's Host: header to
            # match this virtual host. For the default virtual host (this file) this
            # value is not decisive as it is used as a last resort host regardless.
            # However, you must set it for any further virtual host explicitly.
            #ServerName www.example.com

            DocumentRoot /var/www/html

            # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
            # error, crit, alert, emerg.
            # It is also possible to configure the loglevel for particular
            # modules, e.g.
            #LogLevel info ssl:warn

            # For most configuration files from conf-available/, which are
            # enabled or disabled at a global level, it is possible to
            # include a line for only one particular virtual host. For example the
            # following line enables the CGI configuration for this host only
            # after it has been globally disabled with "a2disconf".
            #Include conf-available/serve-cgi-bin.conf

Ненужная информация в файле / etc / host

Это содержимое моего файла host, который находится в / etc /. Мне пришлось попробовать несколько разных вещей, прежде чем PHPMailer смог работать для отправки электронных писем с сайтов , поэтому, скорее всего, есть много ненужных строк.
