Mail Client for Linux?

666, check your PM, ill help you with all your questions on IM or IRC.

Anyway, xiaminan evolution is alot like outlook, if you want something with a similar look to outlook express try Mozilla Thunderbird.
KDE has their new Kontact. I have not tried it out yet, but it is supposed to be more of a bundled ourlook client as well.
No, it's just a mail client. If you want a browser get Firefox. They are both made by mozilla.
