DocFraggle Are you sure you want to run a complex groupware solution without even knowing how to create/edit a file on a Linux system?
nnoblast DocFraggle nano editor can edit and create a file. If you don’t know this, then why are you writing an answer? I start public folder in system Postfix+Dovecot+Sogo but i dont work Dockker and Mailcow.
