SME Server (formerly known as e-smith) is a Linux distribution based on CentOS offering an operating system for computers used as web, file, email and database servers. It employs a comprehensive UI for all management-related tasks and is extensible through templates.

The letters SME stand for Small to Medium Enterprise, as that is the target market of the software. One of the most notable features of this distribution is its template system.

SME Server 9.1 is based on CentOS 6.7 which is based on Red Hat Enterprise Linux (RHEL). Version 32Bit (with PAE Support) and 64bit now available. Running Apache 2.0, MYSQL 5.0, PHP 5, NO additional Addons available on the current “stable” Version (called “SME Contribs”)

Ease of Administration

We use a web-based interface to enable easy administration from any web browser anywhere in the world, very securely protected and accessible remotely via SSH or a VPN, based on strict ACL’s and firewall settings.

File and Print Sharing

The core of any network environment is easy and simple access to shared files and printers. Our server software allows for the easy sharing of files and printers to Windows and Macintosh clients. The “Information Bay” feature provides easy and convenient information, storage and retrieval by multiple groups via web, ftp, or file sharing.

Internet Connection

Small business customers are looking for a simple solution that works with different types of connections to the Internet. Server automates the process of connecting to the Internet. Just connect the server and supply your ISP account information. The server solution acts as a gateway for your entire network and requires no additional client software and minimal configuration. Users can immediately start browsing the Web, using email, and access other Internet services.


With the pervasiveness of email, small businesses increasingly need to support email for all their employees. Server provides a secure reliable email server and allows easy creation of individual and group addresses. For greater versatility, it works with any mail client that uses the industry-standard IMAP, POP3, and SMTP protocols. Secure webmail allows users to access the server from a web browser anywhere on the Internet, to send and receive e-mail via an encrypted (SSL) link.

Antivirus & Antispam

Server comes default with Antivirus and Anti-spam mechanisms based on well known and industry standard ClamAV Antivirus and SpamAssassin products. To reduce the amount of possible unsolicited mail, Server fully automatically updates Antivirus signatures, and Anti-spam rules on a daily bases.


Security is always a priority when a company starts using the Internet. Server offers a multi-layer architecture, protecting the external interface through packet-filtering and service restriction. It offers selective address or port binding, application-level access control lists, and protects the internal network from any intrusion.

Remote Access

Businesses with remote or branch sites or telecommuting employees require remote access to their email and to other resources on the local network. SME Server provides multiple tools such as webmail access to email using any browser, 128-bit PPTP (for secure client-to-server VPNs) and open secure shell (SSH) to provide encrypted access to the internal network and server resources for administrators.

Directory Services

Companies typically require a central directory of email addresses that all users can access. Server features a robust directory service that can be used by most email clients (including Outlook, Outlook Express, and Netscape Communicator). This feature is implemented using the industry-standard LDAP protocol.


Server software supports software RAID 1, 5 and 6, for security and redundancy of Terabytes of data.


Server provides flexible backup methods such as USB Disk backup, tape backup or backup to a remote server. Backups can be fully automated and can include both full and incremental backups.

Automatic Updates

Almost all of the packages that Server includes from 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.
