smtps::connection::submit response

[C0D3RED]

Why am I receiving status code 200 response from gmail smtps server if receipent email does not exists?

            try
            {
                mailio::smtps connection{m_config->host, m_config->port};
                connection.authenticate(m_config->email, m_config->password,mailio::smtps::auth_method_t::START_TLS);
                auto response = connection.submit(msg);
                
                std::cout << response << '\n';
            }
            catch (const std::runtime_error& ex)
            {
                std::cout << ex.what() << '\n';
            }

Because an SMTP server does not check recipients on sending. The email infrastructure is quite different comparing to, for instance, IM server.
