[Mailman-Users] mod_ruid2 and jail apache affects on mailman

Hi,

On our cPanel server, I'm getting the following message in the security advisor:

Apache vhosts are not segmented or chroot()ed.

Enable "mod_ruid2" in the "EasyApache 4" area, enable "Jail Apache" in the "Tweak Settings" area, and change users to jailshell in the "Manage Shell Access" area. Consider a more robust solution by using "CageFS on CloudLinux". Note that this may break the ability to access mailman via Apache.

I'm concerned about the mention of breaking Mailman via apache. Can anyone explain this? I would like to enable these security options, but we host many lists, so don't want to break anything.
