Installation

Docker

docker run -p 1025:1025 -p 8025:8025 smyile/rustmail:latest

See the Docker guide for Compose, persistence, and configuration.

Homebrew

brew install rustmailapp/rustmail/rustmail

If you run RustMail as a service (brew services start rustmail), upgrading to 0.8 migrates the database unattended on the next restart. See Upgrading.

Arch Linux (AUR)

Not published by us

AUR account registration has been closed since June 2026, so we have no way to publish or update rustmail-bin. Whatever the command below installs is not a release we publish or keep current, and it will not track new versions.

Use Homebrew, Docker, or the pre-built binaries instead.

yay -S rustmail-bin

Or with any AUR helper (paru -S rustmail-bin, pacman -S rustmail-bin via chaotic-aur, etc.).

Pre-built Binaries

Download from GitHub Releases: Linux x86_64/aarch64/armv7 (glibc and musl builds), macOS (Intel + Apple Silicon).

From Source

git clone https://github.com/rustmailapp/rustmail
cd rustmail
make build
./target/release/rustmail
