Auf Und Ab Groupware
08/2015 Die Entwicklungen bei Linux-Groupware – eine Zwischenbilanz Sysadmin Auf und ab Groupware 58 Der Groupwaremarkt ist ebenso groß wie schwierig: Microsoft Exchange und Lotus Notes halten die dicken Brocken fest, soziale Netzwerke und Google drängen nach. Freie Software kann gleichwohl auf schöne Erfolge verweisen, gerät aber immer wieder in die Opferrolle – meist wegen externer Finanzierung.

Efficient Spam Filtering System Based on Smart Cooperative Subjective and Objective Methods*
Int. J. Communications, Network and System Sciences, 2013, 6, 88-99 http://dx.doi.org/10.4236/ijcns.2013.62011 Published Online February 2013 (http://www.scirp.org/journal/ijcns) Efficient Spam Filtering System Based on Smart * Cooperative Subjective and Objective Methods Samir A. Elsagheer Mohamed1,2 1College of Computer, Qassim University, Qassim, KSA 2Electrical Engineering Department, Faculty of Engineering, Aswan University, Aswan, Egypt Email: [email protected], [email protected] Received September 17, 2012; revised January 16, 2013; accepted January 25, 2013 ABSTRACT Most of the spam filtering techniques are based on objective methods such as the content filtering and DNS/reverse DNS checks. Recently, some cooperative subjective spam filtering techniques are proposed. Objective methods suffer from the false positive and false negative classification. Objective methods based on the content filtering are time con- suming and resource demanding. They are inaccurate and require continuous update to cope with newly invented spammer’s tricks. On the other side, the existing subjective proposals have some drawbacks like the attacks from mali- cious users that make them unreliable and the privacy. In this paper, we propose an efficient spam filtering system that is based on a smart cooperative subjective technique for content filtering in addition to the fastest and the most reliable non-content-based objective methods. The system combines several applications. The first is a web-based system that we have developed based on the proposed technique. A server application having extra features suitable for the enter- prises and closed work groups is a second part of the system. Another part is a set of standard web services that allow any existing email server or email client to interact with the system. -

OSS-Baserade E-Postlösningar En Fallstudie
Institutionen för kommunikation och information Examensarbete i datalogi med inriktning mot nätverks- och systemadministration, 15 HP Grundläggande nivå Vårterminen 2011 OSS-baserade e-postlösningar En fallstudie Viktor Svensson OSS-baserade e-postlösningar Examensrapport inlämnad av Viktor Svensson till Högskolan i Skövde, för Kandidatexamen (B.Sc.) vid Institutionen för kommunikation och information. Arbetet har handletts av Björn Lundell. 2011-06-01 Härmed intygas att allt material i denna rapport, vilket inte är mitt eget, har blivit tydligt identifierat och att inget material är inkluderat som tidigare använts för erhållande av annan examen. Signerat: _______________________________________________ OSS-baserade e-postlösningar Viktor Svensson Sammanfattning Syftet med studien är att analysera möjligheter och begränsningar med att använda programvaror baserade på öppen källkod för att förvalta en organisations e-post där utkontraktering inte är ett alternativ. Detta baseras på tio krav som identifierats som relevanta i relation till e-postlösningar. Inom studiens omfattning representeras OSS (Open Source Software)-lösningarna av programvarorna Zimbra Collaboration Suite, Citadel och Kolab Server. För att undersöka styrkor och svagheter hos dessa har hybridmetoden action case tillämpats. Genom ett interpretativt och iterativt närmande har representanterna ställts inför de identifierade kraven och deras förmåga att leva upp till kraven har analyserats. Undersökningens resultat visar att majoriteten av kraven kan tillgodoses av lösningarna. -
