Hey my friend, you might want to update the docker compose install script to:
curl -sSL https://github.com/docker/compose/releases/download/v$(curl -Ls https://www.servercow.de/docker-compose/latest)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose

And also the:
./generate_config.sh

Happily done. :-)

You're right!

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

There are still a few things to adjust I think though

Yeah, this gist should be updated to reflect those corrections. For the package installations, use apt instead of apt-get since the commands were not intended to be used by a script.

hello friends,
i have an issue in Mailcow,
i am sending bluk email at once, but i do not know which type of email list i can paste in BCC,
i tried comma (,) dot (.) etc.
i have total email list in excel sheet
please help me how i can send bulk email at once from Mailcow Sogo inbox

Regard

Great tutorial, thanks. Why do you install fail2ban when the mailcow installation already provides a fail2ban instance?

Hey Guys,

Which Static IP SHould I use for better deliveries to gmail ?

means which ISP's IP should I use ??

Thanks In Advance

@priyank2006
Hello I suggest you hetzner in my case the ip of the vps they gave me had problem with outlook but they supported me to get the ips withlisted, care you will not beable to send emails cause their vps ports are limited for outgoing emails until the first bill (1month) I'm still a ovh client, hetzner is cheaper and the support is waayy better even the managment of the vps is sooo much better, I'm looking to migrate there with all my vps ! (maybe try to ask them if they can unlock your ports before the month if you really need it)
Good luck :) !

Thank you so much!

But dear, I Dont want VPS. Only ISP who provides me limitation free Dedicated IP Pool for making SMTP Server.
Thanks for your reply

I recommend instead using this install script for docker as it makes it far easier to manage the versions, removing, and updating:
https://docs.docker.com/engine/install/debian/#install-using-the-repository

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

It throw error

root@box:/opt/mailcow-dockerized# 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
install: target 'fail2ban' is not a directory
install: target 'ufw' is not a directory
Command 'sudu' not found, did you mean:
  command 'tudu' from deb tudu (0.10.4-1)
  command 'sudo' from deb sudo (1.9.9-1ubuntu2.4)
  command 'sudo' from deb sudo-ldap (1.9.9-1ubuntu2.4)
Try: apt install <deb name>
ERROR: Invalid syntax
root@box:/opt/mailcow-d

I think you need
sudo apt-get install fail2ban
sudo apt-get install ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing

Also somebody know how to fix this error?
