Using mutt (or pine), but annoyed that it doesn't give you any notifications when you've received new emails? buzz is a simple tray application that detects new emails on IMAP servers using IDLE (push rather than pull). When it detects unseen messages, it shows a OSD style notification and changes the tray icon to indicate that you have new mail.

This project is a Rust fork of hasmail, which provides basically the same features, and is written in Go.

buzz looks for a TOML configuration file in ~/.config/buzz.toml on startup. The configuration file consists of a number of sections, each corresponding to one account:

[gmail]
server = "imap.gmail.com"
port = 993
username = "jon@gmail.com"
pwcmd = "gnome-keyring-query get gmail_pw"

The value in [] can be anything (though avoid . as it will be parsed as a new TOML section), and is shown in the tooltip when new e-mails arrive for an account. The options for an account are as follows:

• server: The address to connect to. MUST currently be SSL/TLS enabled.
• port: The port to connect to.
• sni_domain: Domain override for TLS Server Name Indication. If not present, it's the same as server.
• server_cert: Absolute path to server certificate. Optional.
• username: Username for authentication.
• pwcmd: Command to execute to get password for authentication.

• click command
• hover tooltip
• customizeable folder
