Spam – Controlling Unsolicited Bulk Email


Spam is a social abuse of Internet messaging services. Technical solutions must follow social consensus about the nature and boundaries of these abuses. To date, no effort to control spam has had widespread, long-term effectiveness. However it is already clear that spam is here to stay and that we must seek to control it, rather than eliminate it. Further many different control mechanisms are needed, including legal, technical and operational.

History of Internet Mail

A round of problematic media activity triggered a request that I produce a "personal" history of Internet mail during the 1970s. The result was:

  • A history of e-mail: Collaboration, innovation and the birth of a system, The Washington Post, 20 March 2012; Local copy / Post original

The community activity surrounding this has resulted in a nascent website:

Here is the background that prompted the invitation to do my article:

Internet Technology Document Suites

What is the set of current documents with the technical details of a particular service?

Answering this question can be daunting, especially when the service has a long history, filled with formal changes, enhancements, errata notes and esoteric lore. This Document Suite wiki provides a home for collaborative, on-going efforts at recording such information about popular Internet capabilities. An Internet service is described by a collection of specification and support documents, along with informal commentary to guide development, deployment, operations and use. This collection forms a Technology Document Suite.
