I'm looking for an e-mail client with good user interface. I'm tired of Thunderbird UI, I don't like it and I feel it to be really clunky. As of late I've been thinking of installing a simple web interface like Roundcube to manage my e-mails. Sadly it doesn't even support PGP or S/MIME (yet). KMail felt like it was going in the right direction. I just wish the thing was usable at all because I can't even create an account with it. So if you have any suggestion for a good e-mail with a decent user inteface let me know. This is of course for offline needs!
Sorry, I use Gmail for all of my personal needs. Stuck with Outlook at work. I thought Thunderbird was most used in Linux?
