How do I ensure that customer emails go to a particular team?

How do I ensure that customer emails go to a particular team?

Hello

I am trying to make customers emails relating to sales/leads go straight into an easily visible/searchable way to access. I believe it will take manpower (daily or weekly) to go through newly created tickets and then edit the classification so it goes to the right people. However I wonder if there is a more automated way to do this:-

a) Set up a new sales Department with emails redirecting here to auto create tickets. Problem is I can't seem to filter the tickets by Department?
b) Set up a new sales Team and access tickets by clicking the Teams Queue section. How do I ensure the tickets that are sent through the sales email address are automatically marked being under the sales Team?
c) An option that I am missing!

Any of these possible? Hopefully I've made sense here!
