Very happy user of Postbox here, and I find it very cheap for how mission critical it is to what I do. I wish it had built-in support for an editable message Priority column (with icons like Eudora used to have), but I've managed to add that in myself with a version of H.Ogi's Priority Switcher extension that I edited myself to work with Postbox 7. I understand some won't like Postbox because it is a proprietary/commercial fork and doesn't have a Linux version. But I wish Thunderbird was up to the quality standard of Postbox.
