Mutt is a mail client for UNIX. It’s text-based, but that’s an advantage to me because I’m forever compiling KDE, so I need something that works while KDE doesn’t. Also, I’m a Vi freak, so I like the Vi keybindings.
My Mutt config files have become quite large over the years. I’ve put them online so you can save yourself time writing your own.
I’ve switched to Mozilla Thunderbird now.
