Have a look at Pegasus www.pmail.com it does most of what you've described, but may still be not smart enough for you in the address book area.

Outlook is great in theory, but a bit of a monster if you really want to use the contacts, schedules etc etc.
And there's no doubt that huge numbers of e-mail viruses exploit the popularity of Outlook.

Maybe look at a dedicated contact management package which interfaces to your e-mail.
Tracker & Goldmine spring to mind as well as Act!
