Brian Haberstroh is a businessman in New Hampshire who once ran Distributed Mail Corporation, which distributed software used to forward e-mail for other companies.
Prior to 2005, Distributed Mail Corporation created a software application called "Virtual Mail Delivery Agent" to end-users which sends permission-based email to addresses supplied by Haberstroh's customers. The application allowed mass emails to get past email filters, but Haberstroh insisted it operated legally and in compliance with CAN-SPAM. He claimed Fortune 1000 companies have licensed his service, though he has not named any of them apparently due to commercial confidentiality agreements. The application basically used the user's computer into a spam distributor of mass emails. [1]
Haberstroh said that all the recipients signed up to receive mail, yet The Spamhaus Project, claimed to have caught many messages from Haberstroh's system in "spam trap" mailboxes with unpublished addresses. Furthermore, when Linford tracked down several users, they claimed to know nothing of the software, indicating that it was installed as malware. Haberstroh denied Linford's accusations and has repeatedly attempted to have Linford's Spamhaus service correct the record. Spamhaus took him off their list of known spammers in 2007. [2]
In 2005, Haberstroh sued one of the recipients of his messages, Jay Stuler of Columbus, Ohio. Stuler complained to Haberstroh's ISP in 2003 after being inundated with spam from Haberstroh's companies, resulting in the companies' ISPs closing down Haberstroh's accounts. Haberstroh in turn sued him for preventing his companies from sending email and thereby causing "financial harm", as well as Stuler's allegedly libeling him as a "criminal". [3] The lawsuit known as Atriks, LLC, Distributed Mail Corporation and Brian Haberstroh v. Jay Stuler, Hillsborough County North Superior Court, Docket No. 04-C-718 has been resolved and judgment has been entered for the Plaintiffs. [4]
Electronic mail is a method of transmitting and receiving digital messages using electronic devices over a computer network. 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, non-commercial proselytizing, or 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.
news.admin.net-abuse.email is a Usenet newsgroup devoted to discussion of the abuse of email systems, specifically through email spam and similar attacks. According to a timeline compiled by Keith Lynch, news.admin.net-abuse.email was the first widely available electronic forum for discussing spam.
A Domain Name System blocklist, Domain Name System-based blackhole list, Domain Name System blacklist (DNSBL) or real-time blackhole list (RBL) is a service for operation of mail servers to perform a check via a Domain Name System (DNS) query whether a sending host's IP address is blacklisted for email spam. Most mail server software can be configured to check such lists, typically rejecting or flagging messages from such sites.
A whitelist or allowlist is a list or register of entities that are being provided a particular privilege, service, mobility, access or recognition. Entities on the list will be accepted, approved and/or recognized. Whitelisting is the reverse of blacklisting, the practice of identifying entities that are denied, unrecognized, or ostracized.
Various anti-spam techniques are used to prevent email spam.
Stephen John "Steve" Linford is a British entrepreneur and anti-spam campaigner best known for founding The Spamhaus Project.
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.
Sanford 'Spamford' Wallace is an Internet spammer. He initially sent junk faxes before coming to notoriety in 1997, promoting himself as the original "Spam King". Wallace's prolific spamming has resulted in encounters with the United States government, anti-spam activists, and large corporations such as Facebook and MySpace.
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. 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.
The Spamhaus Project is an international organisation based in the Principality of Andorra, founded in 1998 by Steve Linford to track email spammers and spam-related activity. The name spamhaus, a pseudo-German expression, was coined by Linford to refer to an internet service provider, or other firm, which spams or knowingly provides service to spammers.
Email harvesting or scraping is the process of obtaining lists of email addresses using various methods. Typically these are then used for bulk email or spam.
SORBS was a list of e-mail servers suspected of sending or relaying spam. It had been augmented with complementary lists that include various other classes of hosts, allowing for customized email rejection by its users.
Robert Alan Soloway is the founder of the so-called "Strategic Partnership Against Microsoft Illegal Spam," or SPAMIS, but is said to be one of the Internet's biggest spammers through his company, Newport Internet Marketing (NIM). He was arrested on May 30, 2007, after a grand jury indicted him on charges of identity theft, money laundering, and mail, wire, and e-mail fraud. He was nicknamed the "Spam King" by prosecutors.
The Abusive Hosts Blocking List (AHBL) was an internet abuse tracking and filtering system developed by The Summit Open Source Development Group, and based on the original Summit Blocking List (2000–2002). Its DNSBLs were shut down on Jan 1, 2015 and now appear to be blacklisting the entire Internet.
The Mail Abuse Prevention System (MAPS) is an organization that provides anti-spam support by maintaining a DNSBL. They provide five black lists, categorising why an address or an IP block is listed:
An email service provider (ESP) is a company that offers email marketing or bulk email services.
An email alias is simply a forwarding email address. The term alias expansion is sometimes used to indicate a specific mode of email forwarding, thereby implying a more generic meaning of the term email alias as an address that is forwarded in a simplistic fashion.
A feedback loop (FBL), sometimes called a complaint feedback loop, is an inter-organizational form of feedback by which a mailbox provider (MP) forwards the complaints originating from their users to the sender's organizations. MPs can receive users' complaints by placing report spam buttons on their webmail pages, or in their email client, or via help desks. The message sender's organization, often an email service provider, has to come to an agreement with each MP from which they want to collect users' complaints.
Email spammers have developed a variety of ways to deliver email spam throughout the years, such as mass-creating accounts on services such as Hotmail or using another person's network to send email spam. Many techniques to block, filter, or otherwise remove email spam from inboxes have been developed by internet users, system administrators and internet service providers. Due to this, email spammers have developed their own techniques to send email spam, which are listed below.
