Willkommen beim SME Server 7

Herzlichen Glückwunsch zur Wahl des SME Servers als Netzwerk und Kommunikationsserver !

Der SME Server ist eine Open-Source Linux-Distribution mit vielen Vorteilen:

  • Einfacher Start: Die Installation und Basiskonfiguration dauert nur 20 Minuten und jede Konfigurationseinstellung kann bequem an einer Web-Oberfläche vorgenommen werden.
  • Sicher und stabil: Der SME Server beinhaltet nur ausgewählte Softwarepakete und ist daher als ISO-Image nur 450 MB groß. Die Verwendung getesteter RPM-Pakete und Unterstützung durch ein komfortables Updatesystem sorgen für enorme Stabilität.
  • Plattformübergreifend und zukunftsicher: Der SME bringt bereits heute alles zur Vernetzung von Windows, Linux und Apple-Systemen mit.
  • Und: Der SME Server ist komplett kostenlos !!
  • Laden Sie sich das ISO-Image unter http://www.smeserver.org herunter

Der Kern des SME Server basiert auf einer unter GPL lizensierten Entwicklungsversion des SME 7.0 alpha von Mitel, die Rechteinhaber für das SME-Konzept ist. Mitel bietet auch den Managed Application Server als käufliche Alternative an, der früher auch als e-Smith-Server bekannt war. Durch großzügige Unterstützung von Mitel bei der Weiterentwicklung des SME Servers wurde der Geist von Open-Source mit der Veröffentlichung des Source-Codes beibehalten.

SME Server 7 verwendet viele Softwarepakete von CentOS und RPMForge. CentOS 4 wird aus öffentlich erhältlichem Source-Code von Red Hat Enterprise Linux entwickelt und ist zu RHEL kompatibel. RPMForge ist eine gemeinsame Plattform verschiedener RPM-Pakete, die nicht in CentOS enthalten sind. Nahezu alle für den SME Server genutzten Pakete von CentOS und RPMForge werden nicht modifiziert. Dadurch profitiert die Stabilität des SME Servers merklich. Diese Pakete sind bereits für andere Distributionen ausführlich auf Stabilität und Sicherheit getestet. Sobald Updates erhältlich sind, können sie auch für den SME Server verfügbar gemacht werden. Bis 2012 werden die Sicherheitsupdates von Redhat/Centos für Centos 4 erhältlich sein.

Server Features

The SME Server server and gateway installs automatically on a PC, converting it to an industrial-strength communications server that optionally allows all of the computers on your network to share a single Internet connection.

In one simple, easy-to-install package, you get:

  • A high performance email server that handles email to and from your users.
  • Enhanced security features that reduce the risk of intrusion.
  • A central file server enabling seamless information exchange among Windows, Macintosh and Unix machines.
  • A web server to host your company web and/or intranet site.
  • Browser based server-manager software that makes it easy to add new user accounts, control remote access, configure network printers, set up workgroups and connect additional networks.
  • Special services that speed web and Internet access, improving the performance of your network.
  • A shared email address book that is maintained automatically.
  • i-bays, a unique communications and collaborative facility that makes it easy for users to work together on projects.
  • Quota Management - you have the ability to set a limit on the amount of a disk space a user can use for files and e-mail.
  • Windows 2000 and XP domain logon support - Previous versions have allowed the server to act as a domain controller for client computers running Windows 95, 98, ME or NT. This version now extends that domain logon support to Windows 2000 and Windows XP.
  • USB printer support - It is now possible to connect the SME Server to a printer via the USB port.
  • Improved Macintosh file sharing support - The server now includes better support for Macintosh file sharing and eliminates some previous cases where Macintosh users were unable to access i-bays.
  • Experimental ISDN card support - While our software has always supported external ISDN adapters, this version now includes experimental support for using an internal passive ISDN card.
  • Use of unmodified packages from upstream providers - Packages from Centos 4 (2.6.9 kernel), Mitel, and other packages from atrpms and rpmforge are used unmodified whenever possible. The result is that any other Redhat EL4 or Centos 4 RPMS should work without modification.
  • Installation on a system with 1 hard drive is automatically set up half of a RAID1 mirror, ready to accept a second drive. Systems with 2 drives are set up as RAID 1; 3-5 drives as RAID5; and 6+ Drives as RAID6.
  • Secure email enhancements. POP3/SSL, IMAP/SSL, SMTP/SSL, SMTP AUTH over SMTP/SSL.
  • Webmail has been upgraded to the latest versions of Horde, Imp, Turba and Ingo from horde.org
  • SMTP Email reception is now handled by qpsmtpd. Advanced but simple to use plugin system to easily install extra functionality and write local rules. Almost all features are implemented in plugins.
  • Antivirus email and hard drive scanning is now provided by ClamAV. Virus definitions are kept up to date automatically, and program updates will be available automatically via the software installer (yum). Plugins are available for 3rd-party (commercial) scanners as well.
  • Email attachment handling: Including the ability to block EXE, ZIP, PIF and automatic conversion of TNEF or UUENCODE encoded attachments to MIME.
  • Spam Filtering with Spamassassin. Automatic tagging with X-spam-status headers, and optional filtering and subject tagging. Configurable rejection levels.
  • Enhancement to the pseudonyms panel. You now have the ability to send (e.g.) support@domain1 and support@domain2 to different places, and you can now enter pseudonyms of pseudonyms.
  • Yum based Software installer panel. Approved contribs and official updates can now be installed in the server-manager. Selectable "Automatically install updates" option.
