sudo systemctl status courier

If Courier MTA is running correctly, you'll see a message indicating that the service is active and running.

Step 5: Configure Firewall

If you have a firewall setup, you'll need to allow traffic to the Courier MTA ports - TCP Port 25 (SMTP) and TCP Port 587 (Submission) - for mail delivery to work. To achieve this, run the following commands:

sudo ufw allow 25/tcp
sudo ufw allow 587/tcp
