OK, I know this is a very general question as there is never an absolute X is the best answer.
I'm looking for an IMAP email client to sync all my email accounts and I've had little experience using these so far, so would like to hear some comments from users.
Mozilla Firefox really sucks more and more with every new version so I'm having my doubts about Thunderbird too. And besides Outlook and Thunderbird, any other good email clients? Don't know much about these actually.
