NeoMutt is a small but very powerful text based program for reading and sending electronic mail under Unix operating systems, including support for color terminals, MIME, OpenPGP, and a threaded sorting mode.
It’s a project of projects, as it brings together many patches to extend Mutt.
NeoMutt is configured through variables which, if the user wants to permanently use a non-default value, are written to configuration files. NeoMutt supports a rich config file syntax to make even complex configuration files readable and commentable.
Because NeoMutt allows for customizing almost all key bindings, there are so-called “functions” which can be executed manually (using the command line) or in macros. Macros allow the user to bind a sequence of commands to a single key or a short key sequence instead of repeating a sequence of actions over and over.
NeoMutt supports a “hook” concept which allows the user to execute arbitrary configuration commands and functions in certain situations such as entering a folder, starting a new message or replying to an existing one. These hooks can be used to highly customize NeoMutt’s behavior including managing multiple identities, customizing the display for a folder or even implementing auto-archiving based on a per-folder basis and much more.

- Attach Headers Color – Color attachment headers using regex, just like mail bodies.
