The Internet Is a Semicommons
GRIMMELMANN_10_04_29_APPROVED_PAGINATED 4/29/2010 11:26 PM THE INTERNET IS A SEMICOMMONS James Grimmelmann* I. INTRODUCTION As my contribution to this Symposium on David Post’s In Search of Jefferson’s Moose1 and Jonathan Zittrain’s The Future of the Internet,2 I’d like to take up a question with which both books are obsessed: what makes the Internet work? Post’s answer is that the Internet is uniquely Jeffersonian; it embodies a civic ideal of bottom-up democracy3 and an intellectual ideal of generous curiosity.4 Zittrain’s answer is that the Internet is uniquely generative; it enables its users to experiment with new uses and then share their innovations with each other.5 Both books tell a story about how the combination of individual freedom and a cooperative ethos have driven the Internet’s astonishing growth. In that spirit, I’d like to suggest a third reason that the Internet works: it gets the property boundaries right. Specifically, I see the Internet as a particularly striking example of what property theorist Henry Smith has named a semicommons.6 It mixes private property in individual computers and network links with a commons in the communications that flow * Associate Professor, New York Law School. My thanks for their comments to Jack Balkin, Shyam Balganesh, Aislinn Black, Anne Chen, Matt Haughey, Amy Kapczynski, David Krinsky, Jonathon Penney, Chris Riley, Henry Smith, Jessamyn West, and Steven Wu. I presented earlier versions of this essay at the Commons Theory Workshop for Young Scholars (Max Planck Institute for the Study of Collective Goods), the 2007 IP Scholars conference, the 2007 Telecommunications Policy Research Conference, and the December 2009 Symposium at Fordham Law School on David Post’s and Jonathan Zittrain’s books. -

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. -

It accepts mail from Mail User Agents (MUAs), mail users (humans), and other MTAs. It then delivers that mail to Mail Delivery Agents (MDAs) on the local machine, or transports that mail to another MTA at another machine. The behavior of sendmail is determined by its command line and by commands in its configuration file. The sendmail program is written and maintained by Eric Allman at sendmail.org. Versions V8.7 and earlier are no longer supported and are no longer considered secure. If you are not currently running V8.8, we recommend you upgrade now.

Today, sendmail development is still drivenbyacontinually changing set of network requirements and user demands. Lately,two new driving forces have also contributed to sendmail development. First, as more open source mail transfer agents, such as Exim and Postfix,become available, a newfriendly competition has developed in which the authors of the various MTAs share their ideas via open source and help to advance open standards as opposed to advancing their own particular implementation. Second, a new“hybrid” company, Sendmail, Inc., has been created to offer commercial versions of the open source software while continuing to fuel open source development. -

This paper is posted at ScholarlyCommons. https://repository.upenn.edu/cis_reports/652 For more information, please contact [email protected]. PMDF - A PASCAL-Based Memo Distribution Facility Abstract This paper describes the implementation of PMDF, a portable Pascal-based internetwork mail router. It includes features such as aliasing, forwarding, queueing automatic routing to network gateways, message batching and message retransmission and is currently being used as a gateway between the Computer Science Network's PhoneNet and local electronic mail systems. PMDF is unique among internetwork mailers in that it is portable. All operating system dependent functions have been isolated to one module and therefore PMDF can be ported to any system that has a Pascal compiler and provides the functions necessary to implement the operating system dependent module.
