Obtaining Exim

Source Distributions

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 exim.org: gpg --auto-key-locate clear,nodefault,wkd --locate-keys [email protected]
or from the Maintainers Keyring

Once you've downloaded the source code, see InstallingExim for help on building and installing Exim.

SCM Access

There are Git repositories.

What's new and change logs

Binary Packages

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.
