access other emails by superuser

access other emails by superuser

I am listed as the super administrator su@ex.com and have set up two additional email accounts 1@ex.com and 2@ex.com, both of those users have their own logins and passwords.  

Is there a way that I can receive emails from those accounts in my su@ex.com account without forwarding the account in the settings of both 1@ex.com and 2@ex.com?  (I want to get the emails and do not want them to be able to stop that).  

If I can, can I mark those emails another color or automatically file them in another folder?  

When I was using gmail and godaddy, I forwarded the email to both my email and those emails, but I cannot find how to do this in zoho.
