mett

A clone of the MUTT e-mail client for accessing Office365 services.

Goal

MUTT is a small, fast, text-based e-mail client for Unix-like systems. mett aims to bring the same keyboard-driven, terminal-first experience to Microsoft Office365, so that mail (and related services) hosted on Office365 can be read, searched, composed and managed from the terminal.

Status

Early stage. mett can sign in to an Office365 account and browse a folder, mutt-style: a message index and a pager. Composing, replying and folder management are still to come.

Quick start

1. Register an app for mett in Microsoft Entra ID; see crates/mett-msgraph/README.md.

2. Create ~/.config/mett/mettrc:

   set my_me = you@example.com
   set from = $my_me realname = "Your Name"
   set folder = msgraph://$my_me/
   set spoolfile = =@inbox
   set msgraph_client_id = <your app's client ID>
   

3. Run mett. The first time, it opens your browser to sign in and shows the sign-in link in a window, in case the browser doesn't open (use set msgraph_auth_flow = device-code over SSH, and mett shows a code to enter instead):

   cargo run -p mett-tui
   

cargo run -p mett-tui -- --demo shows the interface on a sample mailbox without an account.
