Rather not risk myself. Real online dating site reviews since The BIG red flag here is that the guy is asking for money. Senders may go to great lengths to conceal the origin of their messages. Large companies may hire another firm to send their messages so that complaints or blocking of email falls on a third party. Others engage in spoofing of email addresses much easier than IP address spoofing. The email protocol SMTP has no authentication by default, so the spammer can pretend to originate a message apparently from any email address.

Senders cannot completely spoof email delivery chains the 'Received' header , since the receiving mailserver records the actual connection from the last mailserver's IP address. To counter this, some spammers forge additional delivery headers to make it appear as if the email had previously traversed many legitimate servers.

Spoofing can have serious consequences for legitimate email users. Not only can their email inboxes get clogged up with "undeliverable" emails in addition to volumes of spam, they can mistakenly be identified as a spammer. Not only may they receive irate email from spam victims, but if spam victims report the email address owner to the ISP, for example a naive ISP may terminate their service for spamming. Spammers frequently seek out and make use of vulnerable third-party systems such as open mail relays and open proxy servers.

SMTP forwards mail from one server to another—mail servers that ISPs run commonly require some form of authentication to ensure that the user is a customer of that ISP.

Increasingly, spammers use networks of malware-infected PCs zombies to send their spam. Zombie networks are also known as botnets such zombifying malware is known as a bot , short for robot.

In June , an estimated 80 percent of email spam was sent by zombie PCs, an increase of 30 percent from the prior year. For the first quarter of , an estimated , newly activated zombie PCs were brought online each day for malicious activity. This number is slightly lower than the , of the fourth quarter of Brazil produced the most zombies in the first quarter of Brazil was the source of 20 percent of all zombies, which is down from 14 percent from the fourth quarter of India had 10 percent, with Vietnam at 8 percent, and the Russian Federation at 7 percent.

To combat the problems posed by botnets, open relays, and proxy servers, many email server administrators pre-emptively block dynamic IP ranges and impose stringent requirements on other servers wishing to deliver mail.

Forward-confirmed reverse DNS must be correctly set for the outgoing mail server and large swaths of IP addresses are blocked, sometimes pre-emptively, to prevent spam. These measures can pose problems for those wanting to run a small email server off an inexpensive domestic connection.

Blacklisting of IP ranges due to spam emanating from them also causes problems for legitimate email servers in the same IP range. The total volume of email spam has been consistently growing, but in the trend seemed to reverse. The first known spam email, advertising a DEC product presentation, was sent in by Gary Thuerk to addresses, the total number of users on ARPANET was at the time [36] , though software limitations meant only slightly more than half of the intended recipients actually received it.

According to Steve Ballmer , Microsoft founder Bill Gates receives four million emails per year, most of them spam. At the same time Jef Poskanzer , owner of the domain name acme. Because of the international nature of spam, the spammer, the hijacked spam-sending computer, the spamvertised server, and the user target of the spam are all often located in different countries.

In terms of volume of spam: According to Sophos , the major sources of spam in the fourth quarter of October to December were: In terms of number of IP addresses: In terms of networks: Some popular methods for filtering and refusing spam include email filtering based on the content of the email, DNS-based blackhole lists DNSBL , greylisting , spamtraps , enforcing technical requirements of email SMTP , checksumming systems to detect bulk email, and by putting some sort of cost on the sender via a proof-of-work system or a micropayment.

Each method has strengths and weaknesses and each is controversial because of its weaknesses. For example, one company's offer to "[remove] some spamtrap and honeypot addresses" from email lists defeats the ability for those methods to identify spammers. Outbound spam protection combines many of the techniques to scan messages exiting out of a service provider's network, identify spam, and taking action such as blocking the message or shutting off the source of the message.

In order to send spam, spammers need to obtain the email addresses of the intended recipients. To this end, both spammers themselves and list merchants gather huge lists of potential email addresses.

Since spam is, by definition, unsolicited, this address harvesting is done without the consent and sometimes against the expressed will of the address owners. A single spam run may target tens of millions of possible addresses — many of which are invalid, malformed, or undeliverable. Many spam-filtering techniques work by searching for patterns in the headers or bodies of messages.

For instance, a user may decide that all email they receive with the word " Viagra " in the subject line is spam, and instruct their mail program to automatically delete all such messages. To defeat such filters, the spammer may intentionally misspell commonly filtered words or insert other characters, often in a style similar to leetspeak , as in the following examples: This also allows for many different ways to express a given word, making identifying them all more difficult for filter software.

The principle of this method is to leave the word readable to humans who can easily recognize the intended word for such misspellings , but not likely to be recognized by a computer program. This is only somewhat effective, because modern filter patterns have been designed to recognize blacklisted terms in the various iterations of misspelling.

Other filters target the actual obfuscation methods, such as the non-standard use of punctuation or numerals into unusual places. Similarly, HTML-based email gives the spammer more tools to obfuscate text. Inserting HTML comments between letters can foil some filters.

Another common ploy involves presenting the text as an image, which is either sent along or loaded from a remote server. As Bayesian filtering has become popular as a spam-filtering technique, spammers have started using methods to weaken it.

To a rough approximation, Bayesian filters rely on word probabilities. If a message contains many words that are used only in spam, and few that are never used in spam, it is likely to be spam.

To weaken Bayesian filters, some spammers, alongside the sales pitch, now include lines of irrelevant, random words, in a technique known as Bayesian poisoning. A number of other online activities and business practices are considered by anti-spam activists to be connected to spamming. These are sometimes termed spam-support services: Spam-support services can include processing orders for goods advertised in spam, hosting Web sites or DNS records referenced in spam messages, or a number of specific services as follows:.

Some Internet hosting firms advertise bulk-friendly or bulletproof hosting. This means that, unlike most ISPs, they will not terminate a customer for spamming. These hosting firms operate as clients of larger ISPs, and many have eventually been taken offline by these larger ISPs as a result of complaints regarding spam activity.

Thus, while a firm may advertise bulletproof hosting, it is ultimately unable to deliver without the connivance of its upstream ISP. However, some spammers have managed to get what is called a pink contract see below — a contract with the ISP that allows them to spam without being disconnected. A few companies produce spamware , or software designed for spammers.

Spamware varies widely, but may include the ability to import thousands of addresses, to generate random addresses, to insert fraudulent headers into messages, to use dozens or hundreds of mail servers simultaneously, and to make use of open relays.

The sale of spamware is illegal in eight U. So-called millions CDs are commonly advertised in spam. These are CD-ROMs purportedly containing lists of email addresses, for use in sending spam to these addresses. Such lists are also sold directly online, frequently with the false claim that the owners of the listed addresses have requested or "opted in" to be included. Such lists often contain invalid addresses. In recent years, these have fallen almost entirely out of use due to the low quality email addresses available on them, and because some email lists exceed 20GB in size.

The amount you can fit on a CD is no longer substantial. From Wikipedia, the free encyclopedia. Email spam legislation by country. This article possibly contains original research. Please improve it by verifying the claims made and adding inline citations.
