How best to configure more than one email under the same domain

H there,
I just managed to create my emails, it receives and sends, all nice and dandy.
I have two domains setup under one Cyberpanel, each with their own email - lets call them domain1.tld and domain2.tld

I would like to have emails like con[email protected], [email protected], [email protected] etc.

Do I have to create a new inbox for each one of them and the forward it to my main account? So there will be [email protected] (main) and the [email protected], [email protected], [email protected] (each with their own inbox and login password) and then in Cyberpanel under Email>Forwarding I would forward all of them to [email protected]?

My only worry here is that it will create a lot of duplicates and each mail will be stored both on [email protected] and on it’s respective inbox. Is there no better way to set it up?

Many thanks
