Are all of these above users normal and expected as users for the PLesk Obsidian emailer and web server?

If any are unexpected, which ones? Why?
 
Hi, @MHC_1 . The users look pretty standard to me. Here's a comparison with a default freshly set Plesk server on AlmaLinux 9.7:

From what I can see the only users missing on my end are:


Code:
rpc
setroubleshoot
cockpit
rpcuser
tcpdump

However, these look like legitime system users that are missing on my end only due to difference in the installed packages and components.
