How do you get spam on your Email?
From mailing lists. Spammers regularily attempt to get the lists of subscribers to mailing lists [some mail servers will give those upon request], knowing that the email addresses are unmunged and that only a few of the addresses are invalid. When mail servers are configured to refuse such requests, another trick might be used - spammers might send an email to the mailing list with the headers Return-Receipt-To: <email address> or X-Confirm-Reading-To: <email address>. Those headers would cause some mail transfer agents and reading programs to send email back to the <email address> saying that the email was delivered to / read at a given email address, divulging it to spammers. A different technique used by spammers is to request a mailing lists server to give him the list of all mailing lists it carries (an option implemented by some mailing list servers for the convenience of legitimate users), and then send the spam to the mailing list's address, leaving the server to do the hard work of forwarding a copy to each subscribed email address. [I know spammers use this trick from bad experience - some spammer used this trick on the list server of the company for which I work, easily covering most of the employees, including employees working well under a month and whose email addresses would be hard to find in other ways.] From web pages. Spammers have programs which spider through web pages, looking for email addresses, e.g. email addresses contained in mailto: HTML tags [those you can click on and get a mail window opened] Some spammers even target their mail based on web pages. I've discovered a web page of mine appeared in Yahoo as some spammer harvested email addresses from each new page appearing in Yahoo and sent me a spam regarding that web page. A widely used technique to fight this technique is the 'poison' CGI script. The script creates a page with several bogus email addresses and a link to itself. Spammers' software visiting the page would harvest the bogus email addresses and follow up the link, entering an infinite loop polluting their lists with bogus email addresses. From various web and paper forms. Some sites request various details via forms, e.g. guest books & registrations forms. Spammers can get email addresses from those either because the form becomes available on the world wide web, or because the site sells / gives the emails list to others. Some companies would sell / give email lists filled in on paper forms, e.g. organizers of conventions would make a list of participants' email addresses, and sell it when it's no longer needed. Some spammers would actually type E-mail addresses from printed material, e.g. professional directories & conference proceedings. Domain name registration forms are a favourite as well - addresses are most usually correct and updated, and people read the emails sent to them expecting important messages.
