  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

    Thank you, mr-wolf. Fail2Ban is present since 12.5 under security panel from plesk. It's a service that you can activate and configure with a gui. It's a good scanner of log files (Fail2ban) and with 17.5 you have 0.9.6 version. There is a new enhanced version: 0.11.
