Mulberry for anyone looking for a robust mail client. I do not use it for IMAP but only to access several POP3 mail servers, and have found it to be fast and reliable. Two years ago I set out to free myself of AOL. I tried MailSmith, Mail.app, Outlook, Eudora, and even Pine. I found the Mulberry GUI to be incredibly intuitive, with control elements positioned logically and everything behaving exactly as I would have expected. I was quickly sold on the product, sent in my money, and have been using it exclusively ever since. The developers are active and responsive, the discussion list is well attended, and new versions with bug fixes and improvements are released at a comfortable pace. I have had a few crashes with Mulberry, but since I haven't yet upgraded to the latest version I can't count that as negative. I have never, not once, regretted this purchase, or even considered for a moment trying another mail client, something I cannot say about any other class of application.
