The Trusted Email Open Standard (TEOS) is an anti-spam technique proposed by the ePrivacy Group in 2003 at the Federal Trade Commission Anti-Spam Summit. [1]
Edited by Stephen Cobb, CISSP, the 35-page white paper describing the standard was downloaded more than 30,000 times between publication in April 2003 and the end of that year. Many elements of TEOS later appeared in the letter that Microsoft CEO Bill Gates submitted to U.S. Senate Commerce Committee hearings on anti-spam legislation. [2] The letter outlined Microsoft's position on how the spam crisis should be handled. [2]
At its most basic level, TEOS proposes a framework of trusted identity for email senders based on secure, fast, lightweight signatures in email headers, optimized with DNS-based systems for flexibility and ease of implementation. TEOS also provides a common-language framework for making trusted assertions about the content of each individual message. ISPs and email recipients can rely on these assertions to manage their email. [3] [4]
Electronic mail is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail. Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.
Spamming is the use of messaging systems to send multiple unsolicited messages (spam) to large numbers of recipients for the purpose of commercial advertising, for the purpose of non-commercial proselytizing, for any prohibited purpose, or simply repeatedly sending the same message to the same user. While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social spam, spam mobile apps, television advertising and file sharing spam. It is named after Spam, a luncheon meat, by way of a Monty Python sketch about a restaurant that has Spam in almost every dish in which Vikings annoyingly sing "Spam" repeatedly.
Microsoft Outlook is a personal information manager software system from Microsoft, available as a part of the Microsoft 365 software suites. Though primarily being popular as an email client for businesses, Outlook also includes functions such as calendaring, task managing, contact managing, note-taking, journal logging, web browsing, and RSS news aggregation.
Various anti-spam techniques are used to prevent email spam.
The Controlling the Assault of Non-Solicited Pornography And Marketing (CAN-SPAM) Act of 2003 is a law passed in 2003 establishing the United States' first national standards for the sending of commercial e-mail. The law requires the Federal Trade Commission (FTC) to enforce its provisions. Introduced by Republican Conrad Burns, the act passed both the House and Senate during the 108th United States Congress and was signed into law by President George W. Bush in December 2003.
Email spam, also referred to as junk email, spam mail, or simply spam, is unsolicited messages sent in bulk by email (spamming). The name comes from a Monty Python sketch in which the name of the canned pork product Spam is ubiquitous, unavoidable, and repetitive. Email spam has steadily grown since the early 1990s, and by 2014 was estimated to account for around 90% of total email traffic.
Sender Policy Framework (SPF) is an email authentication method which ensures the sending mail server is authorized to originate mail from the email sender's domain. This authentication only applies to the email sender listed in the "envelope from" field during the initial SMTP connection. If the email is bounced, a message is sent to this address, and for downstream transmission it typically appears in the "Return-Path" header. To authenticate the email address which is actually visible to recipients on the "From:" line, other technologies such as DMARC must be used. Forgery of this address is known as email spoofing, and is often used in phishing and email spam.
The Penny Black Project is a Microsoft Research project that tries to find effective and practical ways of fighting spam. Because identifying spams consumes a recipient's time, the idea is to make the sender of emails "pay" a certain amount for sending them. The currency or the mode of payment could be CPU cycles, Turing tests or memory cycles. Such a payment would limit spammers' ability to send out large quantities of emails quickly.
Sender ID is an historic anti-spoofing proposal from the former MARID IETF working group that tried to join Sender Policy Framework (SPF) and Caller ID. Sender ID is defined primarily in Experimental RFC 4406, but there are additional parts in RFC 4405, RFC 4407 and RFC 4408.q
Email marketing is the act of sending a commercial message, typically to a group of people, using email. In its broadest sense, every email sent to a potential or current customer could be considered email marketing. It involves using email to send advertisements, request business, or solicit sales or donations. Email marketing strategies commonly seek to achieve one or more of three primary objectives: build loyalty, trust, or brand awareness. The term usually refers to sending email messages with the purpose of enhancing a merchant's relationship with current or previous customers, encouraging customer loyalty and repeat business, acquiring new customers or convincing current customers to purchase something immediately, and sharing third-party ads.
A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.
ePrivacy Group was a privacy consulting and anti-spam technology firm, founded in 2000 by David Brussin, Stephen Cobb, James Koenig, Michael Miora, and Vincent Schiavone. The team was later joined by privacy pioneers Ray Everett and Terry Pittman.
Ray Everett, formerly known as Ray Everett-Church, is an American attorney, entrepreneur and author. He was dubbed "the dean of corporate Chief Privacy Officers" by Interactive Week Magazine, first creating that title and position in 1999 at Internet advertising company AllAdvantage. In 1997, he was profiled by The New York Times as an influential advocate of responsible online advertising. In 2013 and 2014 Business Insider designated him among the “Most Important LGBT People in Tech.”
A Digital Postmark (DPM) is a technology that applies a trusted time stamp issued by a postal operator to an electronic document, validates electronic signatures, and stores and archives all non-repudiation data needed to support a potential court challenge. It guarantees the certainty of date and time of the postmarking. This global standard was renamed the Electronic Postal Certification Mark (EPCM) in 2007 shortly after a new iteration of the technology was developed by Microsoft and Poste Italiane. The key addition to the traditional postmarking technology was integrity of the electronically postmarked item, meaning any kind of falsification and tampering will be easily and definitely detected.

Watson Research Center in Hawthorne, New York in February 2009, and now works for FutureWei Technologies as a Director of Internet Standards. His work has focused for many years on electronic mail and anti-spam technology, on mobile computing and the Internet of things, and on Internet standards.
The history of email spam reaches back to the mid-1990s when commercial use of the internet first became possible - and marketers and publicists began to test what was possible.
Ipswitch IMail Server is an email server application with groupware functionality that runs on Microsoft Windows OS. It was developed in 1994 by Ipswitch, Inc., a software company based in Lexington, Massachusetts.
There is no commonly agreed single definition of “cybercrime”. It refers to illegal internet-mediated activities that often take place in global electronic networks. Cybercrime is "international" or "transnational" – there are ‘no cyber-borders between countries'. International cybercrimes often challenge the effectiveness of domestic and international law, and law enforcement. Because existing laws in many countries are not tailored to deal with cybercrime, criminals increasingly conduct crimes on the Internet in order to take advantages of the less severe punishments or difficulties of being traced.
SmartScreen is a cloud-based anti-phishing and anti-malware component included in several Microsoft products, including operating systems Windows 8 and later, the applications Internet Explorer, Microsoft Edge. SmartScreen intelligence is also used in the backend of Microsoft's online services such as the web app Outlook.com and Microsoft Bing search engine.
