great tutorial. Thanks. Followed along with your youtube videos. mailserver up and running. some typos here in few commands if i may. eg. sudu incomoing outgoins

Hello, and thanks for your contribution and great video. There are still a few things to adjust I think though:

sudo install fail2ban -->> sudo apt-get install fail2ban sudo install ufw -->> sudo apt-get install ufw sudu ufw default deny incomoing -->> sudu ufw default deny incoming sudo ufw default allow outgoins -->> sudo ufw default allow outgoing

if you are struggling with slow dashboard and high system resource useage, you need to install docker via the original documantation and then enter docker compose up -d because in latest versions it changed from docker-compose to docker compose. İts adding docker to apt-get packet manager and its make way more easier to update to new versions.
The main problem when ı tried this ı had an error called Solved: APT GPG Error NO_PUBKEY, thats because of /etc/opt/keyrings/docker.gpg file is didnt downloaded or it have wrong key, ı solved it with downloading key manualy with this commands:

sudo apt-get install gnupg
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

after this, you will have latest version of docker with connected apt-get. It will make mailcow system way more faster atleast its been like that
