It looks like we here at TUAW are not the only ones who aren't thrilled with Mail.app (I, personally, use Entourage but that's a different post entirely).%uFFFD Someone has posted their top 8 reasons Mail.app sucks. They probably could have pushed their way to 10, but top 10 lists are so 'played,' as the kids say.

I stopped using Mail.app because its spam filtering was terrible compaired to Thunderbird. So I just use thunderbird now.
