Mutt is a command-line email client which can connect to IMAP/POP3 and SMTP protocols as well as read emails from local directories. So, how do I stumbled upon it? I am trying to optimize my workflow. Having to click around a GUI-based email client isn’t my thing. So, I look for alternatives. Why Mutt? because Mutt features a keybinding which is similar to Vim. This means, a single set of shortcuts would work pretty much everywhere.
