(GNU Mailman) Mailing Lists
Usability and efficiency improvements of the (GNU Mailman) mailing lists Rudy Borgstede ([email protected]) System and Network Engineering University of Amsterdam July 5, 2008 Versions Version Date Changes 0.0.1 18 May 2008 First setup of the report 0.0.2 9 June 2008 Release Candidate 1 of the project proposal 0.1.1 17 June 2008 A rewrite of the document because of the change of project result. The project will deliver an advice rather then a product like a patch or add-on for GNU Mailman. This means that the report becomes an consultancy report instead of a project proposal. 1.0.0 30 June 2008 Final version 1 of the report. 1.0.1 1 July 2008 A spelling check of the report. 1.0.2 5 July 2008 Extending the conclusion en future work chapters. Participants Name Contact Information University of Amsterdam Rudy Borgstede (Student) [email protected] Cees de Laat (Supervisor) [email protected] NLnet Michiel Leenaars (Supervisor) [email protected] Abstract This report is the result of a research project of four weeks at the NLnet Foundation1 in Amster- dam. The NLnet Foundation is a foundation who financially supports the open-source community and their projects. The purpose of the project is to improve the usability and the administration of the mailing lists (of the foundation) and giving a more clear view on mailing list server software to anyone who is interested in using mailing list server software or developing new mail or mail- ing list server software. The report describes the research of the usability of several open-source mailing list server software for scalable environments with several well known mail servers. -

Analysis and Performance Optimization of E-Mail Server
Analysis and Performance Optimization of E-mail Server Disserta¸c~aoapresentada ao Instituto Polit´ecnicode Bragan¸capara cumprimento dos requisitos necess´arios `aobten¸c~aodo grau de Mestre em Sistemas de Informa¸c~ao,sob a supervis~aode Prof. Dr. Rui Pedro Lopes. Eduardo Manuel Mendes Costa Outubro 2010 Preface The e-mail service is increasingly important for organizations and their employees. As such, it requires constant monitoring to solve any performance issues and to maintain an adequate level of service. To cope with the increase of traffic as well as the dimension of organizations, several architectures have been evolving, such as cluster or cloud computing, promising new paradigms of service delivery, which can possibility solve many current problems such as scalability, increased storage and processing capacity, greater rationalization of resources, cost reduction, and increase in performance. However, it is necessary to check whether they are suitable to receive e-mail servers, and as such the purpose of this dissertation will concentrate on evaluating the performance of e-mail servers, in different hosting architectures. Beyond computing platforms, was also analze different server applications. They will be tested to determine which combinations of computer platforms and applications obtained better performances for the SMTP, POP3 and IMAP services. The tests are performed by measuring the number of sessions per ammount of time, in several test scenarios. This dissertation should be of interest for all system administrators of public and private organizations that are considering implementing enterprise wide e-mail services. i Acknowledgments This work would not be complete without thanking all who helped me directly or indirectly to complete it. -
Bonus Chapter B Programming for X
Bonus Chapter B Programming for X In this chapter and the next, we’ll take a look at writing programs to run in the usual Linux graphical environment, the XWindow System or X, http://www.x.org/Xorg.html. Modern UNIX systems and nearly all Linux distributions are shipped with a version of X. We’ll be concentrating on the programmer’s view of X, and we’ll assume that you are already comfortable with configuring, running, and using X on your system. We’ll cover ❑ X concepts ❑ X Windows managers ❑ X programming model ❑ Tk—its widgets, bindings, and geometry managers In the next chapter, we’ll move on to the GTK+ toolkit, which will allow us to program user interfaces in C for the GNOME system. What Is X? X was created at MIT as a way of providing a uniform environment for graphical programs. Nowadays it should be fair to assume that if you’ve used computers, you’ve come across either Microsoft Windows, X, or Apple MacOS before, so you’ll be familiar with the general concepts underlying a graphical user interface, or GUI. Unfortunately, although a Windows user might be able to navigate around the Mac interface, it’s a different story for programmers. Each windowing environment on each system is programmed differently. The ways that the display is handled and the programs communicate with the user are different. Although each system provides the programmer with the ability to open and manipulate windows on the screen, the functions used will be different. Writing applications that can run on more than one system (without using additional toolkits) is a daunting task. -
