Kopano, only counts enabled users, so you can have as many groups/distribution lists as you want.

Deleting a user (or disabling Kopano from their account) does not delete the users mailbox, this simply becomes orphaned and can be hooked to a new user account using the "kopano-admin" command line tool, so it's really easy to manage staff changes without losing access to email history, contact, calendar etc.

Also, the "ldapvi" tool is useful to edit the directory in ClearOS when you need to change a users default email address to something other than their login username.
