In this paper we report an investigation into the learning of authorship identification or categorisation for the case of e-mail documents. We use various e-mail document features such as structural characteristics and linguistic evidence together with the Support Vector Machine as the learning algorithm. Experiments on a number of e-mail documents give promising results with some e-mail docume...

We study the performance of the IEEE 802.11 MAC protocol under a range of jammers that covers both channel-oblivious and channel-aware jamming. We consider two channel-oblivious jammers: a periodic jammer that jams deterministically at a specified rate, and a memoryless jammer whose interfering signals arrive according to a Poisson process. We also develop new models for channel-aware jamming, ...

This paper will discuss tracing e-mail headers and issues associated with it. It will address both HTTP & SMTP initiated e-mails. It will discuss different ways used by e-mail senders to evade tracing and workarounds used by investigators to combat them. It will also discuss advanced measures and techniques used by investigators to track emails. The paper will not however discuss any particular...

Spam costs US corporations upwards of $8.9 billion a year, and comprises as much as 40% of all email received [1]. Solutions exist to reduce the amount of spam seen by end users, but cannot withstand sophisticated attacks. Worse yet, many will occasionally misclassify and silently drop legitimate email. Spammers take advantage of the near-zero cost of sending email to flood the network, knowing...

This memo splits message submission from message relay, allowing each service to operate according to its own rules (for security, policy, etc.), and specifies what actions are to be taken by a submission server. Message relay is unaffected, and continues to use SMTP over port 25. When conforming to this document, message submission uses the protocol specified here, normally over port 587. This...

In November 1994 we (members of the former Human Cognition Research Laboratory) ran an experimental version of the Masters level course DM863, ‘Common Lisp for Artificial Intelligence,’ taught as far as possible entirely through the Internet. This report describes this course and outlines some of the experiences and ideas that evolved during this course. Introduction The intention behind this c...

Mail management in an organization is important because it will support performance through information fluency, time efficiency, and labor This study intends to find out how the of e-mail Web applications improves at Waluyo Jati Kraksaan Hospital. The research used field with qualitative descriptive methods, data sources from observation, in-depth interviews informants, Data credibility test u...

With the increasing popularity of a E-mail users, E-mail spam problem growing proportionally. Spam filtering with near duplicate matching scheme is widely discussed in recent years. It is based on a known spam database formed by user feedback which cannot fully catch the evolving nature of spam and also it requires much storage. In view of above drawbacks, we proposed an effective spam detectio...

Michael D. Kudlick MDK (SRI-ARC) NIC 14798 8-MAR-73 Network Mail Meeting Summary Introduction The purpose of this RFC is to briefly summarize, from the NIC’s viewpoint, the principal conclusions reached at the Network Mail Meeting held Friday, February 23 1973, at SRI-ARC. Please refer to RFC #475 (NIC 14919) for Abhay Bhushan’s comprehensive summary of the issues discussed at the meeting. Ther...

Companies conduct world-wide collaborations which often involve asynchronous work with group members in di erent time-zones. In asynchronous work, the participants can easily waste days just clarifying questions because feedback is slow. For e cient collaborations, accurate \handing-o " of work between participants is crucial. Therefore, messages exchanged between collaborators should not conta...
