Central email with three users - Possible?

Hi, we are new to world of mac & it's OS, what I would like to know, is it possible to have each user account (Me, Wife & daughter) to be able to view our own emails on our own accounts.

At the moment all the emails are going through my account (set up as admin). If it is possible, does that mean that the emails would be seperate from each person or can I keep all the emails in a central are like iTunes is set-up at the moment. One central are with all three accounts looking at same place.

Thanks for the help

You can each have a user, each with one or more discrete email accounts, yes.
