Hi all. I'm on the verge of transitioning from viewing my email in Safari/Chrome to using a dedicated mail app. Mail.app seems to be slow in pulling in new mail, Thunderbird is just plain archaic & ugly, Sparrow is pretty but limited (no Gmail priority Inbox view!). The most viable option I've tested is Postbox 3.0. It does everything that I want, is pretty and is quite fast. However, it uses up a HUMONGOUS amount of RAM! Via Activity Monitor, I see it takes up at least 200MB+ of RAM, and the most I've seen it use is 600+MB! Granted my Gmail account is pretty large (15000 emails and counting), but I've tried reducing it by unsubscribing from all unnecessary folders & indexing all the necessary ones (indexing has been completed btw). Resource usage is important for me, as my MBA only has so much RAM. Any idea why Postbox does this?
