• 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.

Can you limit Email Clients by Ip Addresss ( dovecot imap settings?)
if people spam our emails with user and pass to connect and spam from outside of our app?
 
This is an easy task for Fail2Ban. Plesk comes with a jail named "Dovecot". Simply activate that jail. It'll monitor the mail log for failed login attempts and ban the IP addresses of the users who send n false logins.
