If you are using "Debian Squeeze" then please follow the new tutorial. A spanish translation of this tutorial is also available courtesy of José Ramón Magán Iglesias. What this tutorial is about You surely know the internet service providers that allow you to rent a domain and use it to receive emails. If you have a computer running Debian which is connected to the internet permanently you can do that yourself. You do not even need to have a fixed IP address thanks to dynamic DNS services like dyndns.org. All you need is this document, a cup of tea and a little time. When you are done your server will be able to... receive and store emails for your users from other mail servers let your users retrieve the email through IMAP and POP3 even with SSL to encrypt to connection receive and forward ("relay") email for your users if they are authenticated offer a webmail interface to read emails in a web browser detect most spam emails and filter them out or tag them License/Copyright This tutorial book is copyrighted 2009 Christoph Haas (email@christophhaas.de).

The Bioinformatics Lab SS11 Mail / DNS Antonia Stank 20.06.2011
The bioinformatics lab SS11 Mail / DNS Antonia Stank 20.06.2011 1 Introduction The Domain Name System (DNS) is a one of the most important systems in the network. It is a hierarchical naming system which is built on a distributed database for computers, services or any resource connected to the Internet. The DNS can also be used in a private or local network. The main service of a DNS is that it serves as a kind of “phone book” for the internet or local network by translating user-friendly hostnames into specific IP addresses. For example it is much easier to remember the internet address: www.google.de than the corresponding IP address 209.85.148.99. So it can translate names to numbers and vice versa and helps therefore to connect on a specific IP address without knowing the number. An e-mail-server or just mail server is a server which can handle the mail traffic. It is necessary for sending, receiving, forwarding and saving mails. An Internet Message Access Protocol (IMAP) server is a server that provides the usage of the most prevalent IMAP protocol. There is also another common protocol which is the so called Post Office Protocol (POP). The advantage of the IMAP is that it allows an e-mail client access to a remote mail server. The e-mail clients using IMAP leave the mails on the server until they are explicitly deleted by the user. This and some other advantages make it possible to allow multiple clients to have access to the same mailbox. -
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. -
Ubuntu Server Guide Basic Installation Preparing to Install
Ubuntu Server Guide Welcome to the Ubuntu Server Guide! This site includes information on using Ubuntu Server for the latest LTS release, Ubuntu 20.04 LTS (Focal Fossa). For an offline version as well as versions for previous releases see below. Improving the Documentation If you find any errors or have suggestions for improvements to pages, please use the link at thebottomof each topic titled: “Help improve this document in the forum.” This link will take you to the Server Discourse forum for the specific page you are viewing. There you can share your comments or let us know aboutbugs with any page. PDFs and Previous Releases Below are links to the previous Ubuntu Server release server guides as well as an offline copy of the current version of this site: Ubuntu 20.04 LTS (Focal Fossa): PDF Ubuntu 18.04 LTS (Bionic Beaver): Web and PDF Ubuntu 16.04 LTS (Xenial Xerus): Web and PDF Support There are a couple of different ways that the Ubuntu Server edition is supported: commercial support and community support. The main commercial support (and development funding) is available from Canonical, Ltd. They supply reasonably- priced support contracts on a per desktop or per-server basis. For more information see the Ubuntu Advantage page. Community support is also provided by dedicated individuals and companies that wish to make Ubuntu the best distribution possible. Support is provided through multiple mailing lists, IRC channels, forums, blogs, wikis, etc. The large amount of information available can be overwhelming, but a good search engine query can usually provide an answer to your questions. -
Macsysadmin 2009 Presentatio
Slide 1 SpamAssassin Way more than the Mac OS X Server GUI shows Presented by: Kevin A. McGrail Project Management Committee Member of the Apache Software Foundation SpamAssassin Project & President, PCCC September 16, 2009 Good Afternoon, My name is Kevin A. McGrail. If you read my biographyi for this conference, you’ll know already that I hate Spam and enjoy greatly fighting spammers. You’ll also know that I love all types of computers and use a wide variety of machines & operating systems. But I’m definitely old-school in my love for the command line interface. This doesn’t mean I don’t think that Apple’s OS X is the most beautiful pairing of a rock-solid CLI with a beautifully polished GUI. But it does mean that while we are here to talk about Mac system administration, the configuration of SpamAssassin is largely not server specific and most of the heavy- handed configuration changes will be done behind the scenes using the CLI. So let’s get started by talking about the definition of Spam. Page 1 of 67 Slide 2 What is Spam? •Spam is NOT about content, its about CONSENT. – Consent: to give assent or approval : agree <consent to being tested> Merriam‐Webster Dictionary •What is SPAM vs. spam? September 16, 2009 Chris Santerre gave the best definition of Spam I’ve ever seen. He based the definition of Spam on CONSENT not content because consent is when you give approval to someone to send you e-mails. Many people try and use various legal definitions such as CAN-SPAM in the US. -
