  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • 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.

I have upgraded one server from 10.3 to latest PLESK and I get problems with some mail accounts.
Some clients started to complain that cannot login anymore to webmail (ATMAIL)
I have tested some of my accounts and working, and tested other accounts and not working indeed.
Also I have the same test by telnet 143 and same result, login failed for some users and working for others.

I like this vodooo things, I have tried to fix mailboxes, but nothing. Anyone have an idea where to check? in maillog no clue on thislogin errors.
