I have 50 pages and over 2000 emails. Guess I should get started. lol
Heh. You can get 100 to show on a page. If you assume all of them are spam, it's pretty quick chore - but if you aim to read a couple thousand subject lines, well, dang, that's a tough chore.
I get a few thousand spams a month, so run an aggressive (local) spam filter on what fetchmail brings home.
