What's the equivalent of Microsoft Outlook on the Mac? MS Entourage or Apple Mail?

Outlook on PC has email (I have like 7 email addresses that I want to tie into the Mac program), calendar, contacts, tasks, and notes – is there any program on the Mac that has all these features too? or are they all separate programs? I also need email rules like MS Outlook has to have certain emails from different email addresses be automatically routed into different folders inside the email client. Any insight is much appreciated.
