GUI imap client

[soralx at cydem.org]

can anyone kindly recommend a decent GUI imap client? I used KMail for
quite a while and didn't complain, but decided to move away from it
(slow, stores message flags in some weird way usable only to itself,
fancy, requires KDE, etc). So I tried sylpheed-claws (I often heard
compliments in it's address, since the times of stuphead). Well, it
turned out to be an ugly one: has a nasty habit of coredumping a dozen
times per day, never saves any preferences, completely untunable (hell,
I can't even change the vertical dimension of so-called 'Folder' list
-- what a waste of space!), just riddled with bugs. Not very usable :(
Is there a kind of compromise between KMail and sylpheed? (or something
original wouldn't hurt either ;)
