Issue Unable to install Plesk Email Security

[Cav3n]

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?

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
