A terminal email client for Maildir folders, written in Rust.

• Threaded email list with tree indentation
• Diff/patch syntax highlighting in email bodies
• Reply-all composition with quoting in $VISUAL/$EDITOR
• Compose new emails from scratch
• Draft saving to a dedicated Drafts mailbox
• Read/unread tracking via Maildir filename flags
• Multiple mailboxes with sidebar
• Tab-based email viewing
• Live search filtering by subject
• Unread-only filter toggle
• Sort threads by most-recent activity (ascending / descending)
• SMTP sending via STARTTLS
• Periodic background sync via a configurable shell command (e.g. mbsync)

Create ~/.config/brew/config.toml:

[smtp]
host     = "smtp.gmail.com"
port     = 587
name     = "Name Surname"
username = "you@example.com"
password = "app-password"

[[mailbox]]
label = "INBOX"
path  = "/home/you/Mail/INBOX/"

[[mailbox]]
label = "Work"
path  = "/home/you/Mail/Work/"

# Optional: a mailbox labelled "Drafts" is treated specially.
# Pressing Enter on a draft reopens it in the editor.
# The send dialog offers a "Save as draft" option.
[[mailbox]]
label = "Drafts"
path  = "/home/you/Mail/Drafts/"

# Optional: run a shell command every N seconds to sync mail.
# Errors are shown in the status bar; the UI is never blocked.
[sync]
command  = "mbsync -a"
interval = 60

Optional files (plain text, loaded from ~/.config/brew/):
