  • Make sure that no other application is interferring with mailcow's configuration, such as another mail service

  • A correct DNS setup is crucial to every good mailserver setup, so please make sure you got at least the basics covered before you begin!

  • Make sure that your system has a correct date and time setup. This is crucial for stuff like two factor TOTP authentication.
