• 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.

read webmail attachment issue

In the default install we had a problem with attachments being attached as 0 bytes (or close to it). We have to change the PHP temporary files directory (PHP.ini) and assign permissions properly to get it resolved.

What line have you changed to make it work?

You should open your PHP Ini and make sure the line which contains the Temporary files directory points to a directory which has permissions for the IIS User (IUSR) to write / read files. Our problem was that it was set to a path that did not exist on the server.
