  • 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.

Issue Unable to install Plesk Email Security

C

New Pleskian
Server operating system version
CentOS 6.10
Plesk version and microupdate number
18.0.31
Hi,
I tried to install Plesk Email Security (1.3.3-307) but got the following error message
Surprisingly, the extension is still listed as installed. However, opening it returns another error about Dovecot not being installed or activated.

I'm running CentOS 6.10, Plesk 18.0.31.

Does anybody have a clue what's going wrong?
 
Sorry, herer comes the error message..

Regarding the epel rpm error, you could try to change the baseurl in /etc/yum.repos.d/epel.repo to something like this:

baseurl=http://archives.fedoraproject.org/pub/archive/epel
