Hi, i'm using a VPS CENTOS 7.9 kvm v98.0.6,
We try not to change any code, we use it just to add Domains, and to do some DNS stuff, however, a few days I had to restart and upgrade the server and everything started.
My users are experiencing problems with email, everyone in the company uses Outlook as a desktop client, and starting a week ago or so, the outlook has been prompting every user to log in again, as if the password for their emails was changed, or as if some configuration in the server was made.
I tried to log on to the server without success regardless of trying with cPanel or WHM, so I restarted it. It started working again, but with the same issue, so I checked the status, and services like Exim and Imap are constantly going down and up. I tried looking for errors, or a pattern without success.
It is intermittent, therefore I'm not sure where to look or what to do, any insight would be good.
