sudo swupd update

Then, you can install the Citadel package by running this command:

sudo yum install citadel

Step 3: Configure Citadel

Once the installation process completes, you need to configure the Citadel server. To do that, run the following command:

sudo /usr/sbin/setup-citadel

This will open the Citadel setup wizard, which will guide you through the configuration process.

Step 4: Access Citadel

After the configuration process is complete, you can access the Citadel web interface by pointing your browser to http://localhost:2000.

Alternatively, you can use an email client like Thunderbird or Outlook to connect to the Citadel server using the following settings:
