Spam Blocking Software For A Server?

I recently purchased an existing domain name, the problem is I am receiving 500 spam emails a week on this name.

Can anyone suggest any software that can be added to a server to block/ reduce spam on this domain name? As mail is even getting to people I have set up forwarding rules for and it is very embarrassing!

Any help would be very much appreciated.
