The last time I tried to use the built in mail app (about a year ago?) I was met with some pretty serious bugs that made it unusable. Not to mention those smart filters didn't work.
It sucks that Apple has let it get so bad, but I personally wouldn't consider Mail part of the OS. It's just a built in App like garage band or something.
