套件： aerc (0.8.2-1ubuntu0.2)

World's Best Email Client

Some of its more interesting features include:

 - Editing emails in an embedded terminal tmux-style, allowing you to check on
   incoming emails and reference other threads while you compose your replies
 - Render HTML emails with an interactive terminal web browser, highlight
   patches with diffs, and browse with an embedded less session
 - Vim-style keybindings and ex-command system, allowing for powerful
   automation at a single keystroke
 - First-class support for working with git & email
 - Open a new tab with a terminal emulator and a shell running for easy access
   to nearby git repos for parallel work
 - Support for multiple accounts, with support for IMAP, Maildir, SMTP, and
   sendmail transfer protocols
 - Asynchronous IMAP support ensures the UI never gets locked up by a flaky
   network, as mutt often does
 - Efficient network usage - aerc only downloads the information which is
   necessary to present the UI, making for a snappy and bandwidth-efficient
   experience 100% free and open source software!
