The primary source distribution is from the main exim.org site. See https://downloads.exim.org/exim4/ for the source packages, which are always accompanied by detached OpenPGP (aka "PGP", "GPG") Signatures.
All releases are PGP-signed by an OpenPGP key with a uid in the
@exim.org domain. All valid keys can be retrieved via WKD from
gpg --auto-key-locate clear,nodefault,wkd --locate-keys PERSON@exim.org
or from the Maintainers Keyring
Once you've downloaded the source code, see InstallingExim for help on building and installing Exim.
There are Git repositories.
From 2022-05-25, the latest version of Exim is 4.96.
The popular exiscan-acl patch code has been incorporated into Exim from version 4.50 onwards. The distributors' patch for dynamically loadable lookups has been incorporated into Exim from version 4.74 onwards.
Binary packages are all built by third parties, and not the EximDevelopers. Packaging issues should be reported to the packagers. In general binary packages include the exiscan extensions, however the build configuration is a decision made by the packager.
Red Hat / Fedora Linux Distributions
For Fedora, exim packages are distributed as follows:
- Fedora Core 3 (now EOL): as part of the base OS
- Fedora Core 4+: as part of the Fedora Extras repository, maintained by DavidWoodhouse
Earlier releases were also built for FC2 and old RHL releases.
For Red Hat Enterprise, Exim packages are distributed as follows:
- RHEL4: Exim 4.43 is available
In general, due to the similarities between Fedora and Red Hat Enterprise, the latest Exim packages from Fedora Extras can usually be rebuilt fairly easily (i.e. with minimal or no modifications) on modern versions of Red Hat Enterprise (i.e. RHEL3, RHEL4) and variants such as CentOS, White Box Enterprise Linux etc.
- Some older packages are also built for FC1 and several RHL varients by TimJackson - those RPMs can be found here but are not currently being maintained.
- The ATrpms RPM repository carries current Exim rpms for many Red Hat and Fedora distributions.
SuSE/Novell SUSE Distributions
Binary packages (unsupported by Novell/SuSE) can be found here.
Debian GNU/Linux ships packages for Exim 4 (called exim4).
There are two variations: exim4-daemon-light, or exim4-daemon-heavy which differ in the compiled-in feature set.
Information about the Exim 4 Package, including update hints, can be found in /usr/share/doc/exim4-base/README.Debian.html, or on the Web in https://salsa.debian.org/exim-team/exim4/tree/master/debian.
There is a dedicated mailing list for exim on Debian. You can subscribe via https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/pkg-exim4-users

Documentation source packages are available from the same place as the source distributions. The main documentation is also available as browsable HTML on https://www.exim.org/
