Spam<\/a> is one of the biggest problems on the Internet. The \"data garbage\" spreads mainly via e-mail and has many unpleasant consequences. Private individuals and companies receive unwanted emails every day. The large volume of junk data sent via the Internet entails high costs and a great deal of time. The Spam House<\/a>.org published on its website<\/a> has an enormous amount of information about spam senders and operates a freely accessible RBL server. Various blacklists can be used to IP addresses<\/a> and domain names of known spammers are blocked. Problems with e-mail delivery can occur if Spam House<\/a> discontinues support for public DNS resolvers.<\/p>\n

Types and effects of spam<\/h2>\n

Unsolicited mass e-mails are one of the typical types of Spam<\/a>. The messages are sent to a very large number of recipients. As a rule, these are e-mail marketing campaigns and other advertising-related purposes. Commercial e-mails are also sent in large quantities via the Internet. The content of these emails includes offers for casinos, sexual enhancers, financial services and software. Other types include collateral spam, backscatter and Usenet spam. Spam or junk causes considerable damage in terms of international communication. The biggest problems are the additional data volumes and the time required to get rid of the spam. Reading and sorting out unwanted e-mails, often referred to as junk e-mails, takes a lot of time. In most companies, the Internet is not billed according to usage time, but according to data volume. A large amount of spam increases the amount of data and therefore also increases the company's monthly costs. The large number of spam mails increases the processing time of normal mails and this in turn has a negative effect on productivity. In the USA alone, unwanted emails cause over 22 billion US dollars worth of damage every year. For these reasons, there are many companies and organizations that take action against spam and maintain black and grey lists. Spamhaus.org is one of the best-known providers that operates a publicly accessible RBL server. A Real-time Blackhole List is a blacklist that can be queried in real time and can be used to classify spam emails.<\/p>\n

What is Spamhaus.org?<\/h2>\n

Spamhaus is an international non-profit organization and was founded in 1998. Its headquarters are located in Geneva. The organization has set itself the task of tracking spam activities on the Internet and those responsible for them. In the \"Records Of Known Spam Operations\", Spamhaus publishes many important details about the spammers. They even name the spammers and publish some photos. This information comes from many different sources and most of it is publicly available. The information is only published if there are at least 2 sources to back it up. Based on this information, other users can decide whether to classify a particular email as spam. Spamhaus operates several DNS-based blackhole lists and real-time blackhole lists. It has one of the largest DNS infrastructures in the world. Spamhaus' network consists of more than 80 public DNSBL servers located in 18 different countries. Spamhaus' servers are mainly used by Internet email providers, corporations, governments and military networks. Many corporate email servers use these blocklists to Filter spam<\/a> and thus ensure the integrity of e-mail communication. Spamhaus offers this entire service free of charge.<\/p>\n

The Zen list of Spamhaus at a glance<\/h2>\n

The mail accounts of around 2 trillion Internet users are protected by the DNSBL lists of the Spamhaus organisation. The company employs independent investigators around the world. The various blacklists of Spamhaus can be used free of charge for non-commercial purposes. Up to 100,000 emails per day is the maximum limit. Spamhaus provides more than 50 public servers for this purpose. If you exceed this volume or use the lists commercially, you have to license the use at Spamhaus.<\/p>\n

Spamhaus operates several blacklists<\/h2>\n

The Spamhaus Block List (SBL) contains numerous IP addresses from which the organization believes that you should not receive email for your own safety. The basis for the entries are various spam events and these are analyzed by Spamhaus and then entered into the database. The Exploits Block List (XBL) contains the addresses of hacked desktop PCs and servers that belong to a botnet. Spamhaus receives the XBL data from the open proxy entries of njabl.org and from the lists of cbl.abuseat.org.<\/p>\n

The Policy Block List (PBL) lists IP addresses that are used by the large Internet Service<\/a> providers (ISPs) have been classified as so-called dial-up ranges. Many experts are of the opinion that no mails should be sent directly from such addresses. Spamhaus itself does not define the IP addresses on the policy block list. This is done exclusively by the service providers themselves. The ZEN list (zen.spamhaus.org) is a combination of data from the 3 lists XLB, SBL and PBL. If you want to query all 3 lists anyway, you can query the ZEN list directly and save time.<\/p>\n

A major problem that can arise from being listed on the DROP list (Don't Route Or Peer) is that officially registered IP networks of acquired or insolvent companies that are not currently in use can be hijacked via the BGP routes and misused for other purposes, such as spam or cyber attacks. You should always block addresses that are located at drop.spamhaus.org. The Domain<\/a> As the name suggests, Block List (DBL) does not contain addresses, but domains. Only domains that are used for phishing purposes, for example, or that are advertised in spam emails are listed.<\/p>\n
