Weird, I have exactly the opposite experience with spam -- my self hosted setup does better than gmail. Wrote this a while back, but still holds true: https://news.ycombinator.com/item?id=5441542
I don't have nearly the volume of email you do though. My inbox has 20K, probably another 70K in other folders. Thunderbird is fine for me, except I'd like a more powerful and faster search. Gmail search is not good enough, though much better than other webmail clients I've tried.
