Rspamd supports the following .deb based distributives:

• Debian bookworm (since 3.5)
• Debian bullseye
• Ubuntu focal (since 2.5)
• Ubuntu jammy (since 3.3)

To install the rspamd stable¹ apt repository, please use the following commands:

#apt update # if running a minimal system
#apt-get install sudo # if running a minimal system
sudo apt-get install -y lsb-release wget gpg  # optional
CODENAME=`lsb_release -c -s`
sudo mkdir -p /etc/apt/keyrings
wget -O- https://rspamd.com/apt-stable/gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/rspamd.gpg > /dev/null
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/rspamd.gpg] http://rspamd.com/apt-stable/ $CODENAME main" | sudo tee /etc/apt/sources.list.d/rspamd.list
echo "deb-src [arch=amd64 signed-by=/etc/apt/keyrings/rspamd.gpg] http://rspamd.com/apt-stable/ $CODENAME main"  | sudo tee -a /etc/apt/sources.list.d/rspamd.list
sudo apt-get update
sudo apt-get --no-install-recommends install rspamd

For Hyperscan and LuaJIT information see the FAQ.

For experimental² branch replace apt-stable with just apt:

#apt update # if running a minimal system
#apt-get install sudo # if running a minimal system
sudo apt-get install -y lsb-release wget gpg  # optional
CODENAME=`lsb_release -c -s`
sudo mkdir -p /etc/apt/keyrings
wget -O- https://rspamd.com/apt-stable/gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/rspamd.gpg > /dev/null
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/rspamd.gpg] http://rspamd.com/apt/ $CODENAME main" | sudo tee /etc/apt/sources.list.d/rspamd.list
echo "deb-src [arch=amd64 signed-by=/etc/apt/keyrings/rspamd.gpg] http://rspamd.com/apt/ $CODENAME main"  | sudo tee -a /etc/apt/sources.list.d/rspamd.list
sudo apt-get update
sudo apt-get --no-install-recommends install rspamd

For ASAN² branch install rspamd-asan package instead of rspamd (since 3.5).

Please bear in mind, that you might also need debug symbols package for Rspamd to be able to fill bug reports about possible crashes. Debug symbols are placed in rspamd-dbg (or rspamd-asan-dbg) package and could be safely installed even in the production environment. Check the quick start document for further steps.

Packages support policy

Check the support policy document to clarify what OS versions are supported by Rspamd packages.

Debian standard repos notes

Please DO NOT use those packages, as they are likely outdated and are not supported by Rspamd project in any way (so any associated issue will likely be closed automaticall). If you decide to use those packages then please address any issues to the Debian package maintainers.

Rspamd is also supported on the following Linux distributions:

• Alpine Linux
• Arch Linux
• Gentoo Linux
• OpenSUSE
• Void Linux

Alpine Linux

Rspamd is available in the community repository

Arch Linux

Rspamd is available in the community repository

Gentoo Linux

Ebuilds for Gentoo Linux users are available in the main Gentoo Portage repository.

OpenSUSE

Packages for OpenSUSE Leap & Tumbleweed are available on OBS.

Void Linux

Packages for Void Linux are available in the main package repository.

Rspamd has been ported to the following BSD like operating systems:

• FreeBSD
• NetBSD
• OpenBSD
• macOS (using MacPorts)

FreeBSD users can install Rspamd from ports or use the experimental line of packages by rspamd-devel port.

Users of NetBSD (and other systems with pkgsrc) can use pkgsrc.

OpenBSD users can use ports.

macOS users can install from MacPorts:

sudo port install rspamd
sudo port load rspamd

If there are no packages for your system or you want custom build options you can also build rspamd from the source code. To do that grab the source from github using git:

git clone --recursive https://github.com/rspamd/rspamd.git

Build requirements

Rspamd requires several 3-rd party software to build and run:

• openssl - cryptography and SSL/TLS Toolkit
• glib2 - common purposes library
• ragel - state machine compiler.
• LuaJIT - jit compiler for lua programming language. Plain Lua should work as well.
• cmake - build system used to configure rspamd
• sqlite3 - embedded database used to store some data by rspamd
• libmagic - common library for detecting file types
• libicu - unicode library
• PCRE - regular expressions library
• Hyperscan/Vectorscan - optional regexp performance boost library
• zlib - compression library

You can either install them from sources or (recommended) install using package manager of your system.

It is also highly recommended to use Redis as it can be used by many Rspamd modules to improve their filtering quality (some modules will be turned off completely without Redis).

It is also recommended to build Rspamd with Hyperscan (x86_64 only) or Vectorscan (aarch64/ppc64le) and Jemalloc to improve performance.

Build process

To build rspamd we recommend to create a separate build directory:

$ mkdir rspamd.build
$ cd rspamd.build
$ cmake ../rspamd -DENABLE_HYPERSCAN=ON -DENABLE_LUAJIT=ON -DCMAKE_BUILD_TYPE=RelWithDebuginfo
$ make
# make install

Alternatively, you can create a distribution package and use it for build your own packages. Here is an example for Debian GNU Linux OS:

$ mkdir rspamd.build
$ cd rspamd.build
$ ./dist.sh
$ tar xvf rspamd-<rspamd_version>.tar.xz
$ cd rspamd-<rspamd_version>
$ debuild
