SME Server v7.5 is the latest stable version of the award-winning Mitel/e-smith based Server and Gateway, the world's leading open-source server software for small and medium-sized enterprises. The heart of SME Server 7 is based on the GPL'd sources of the unsupported developer release of SME 7.0 alpha from Mitel, who is the copyright holder for much of what makes SME Server what it is. Mitel's commercial offering is known as the "Mitel Managed Application Server", and in the past was known as e-Smith. Mitel has been very generous to fund development of the alpha and beta versions and to keep to the spirit of the GPL by sharing their source code freely.

SME Server v8.0 is the latest stable version of the award-winning Mitel/e-smith based Server and Gateway, the world's leading open-source server software for small and medium-sized enterprises. The heart of SME Server 8 is based on the GPL'd sources of the unsupported developer release of SME 7.0 alpha from Mitel, who is the copyright holder for much of what makes SME Server what it is. Mitel's commercial offering is known as the "Mitel Managed Application Server", and in the past was known as e-Smith. Mitel has been very generous to fund development of the alpha and beta versions and to keep to the spirit of the GPL by sharing their source code freely.

SME Server 7 uses many packages from CentOS and RPMForge. CentOS 4 is built from publicly available open source Red Hat Enterprise Linux SRPMS and aims to be binary compatible. RPMForge is a collaborative effort of several RPM packagers that build RPMs not included with CentOS. Almost all of the packages that SME Server includes from these upstream vendors are included unmodified. The purpose of doing so is to take advantage of the stability that comes from the huge user base that uses these packages, for security, and to allow automatic updates as soon as an update is available from the upstream vendor. Security updates from Redhat/Centos should be available until 2012 for Centos 4.

Almost all of the packages that SME Server includes from these upstream vendors are included unmodified. The purpose of doing so is to take advantage of the stability that comes from the huge user base that uses these packages, for security, and to allow automatic updates as soon as an update is available from the upstream vendor. Security updates from Redhat/Centos should be available until 31 Mar 2017 for Centos 5.
