In my last post i was discussed How to protect spam emails .So this is one of the technique
For some e-mail users, a sensible, sufficient, and very simple approach to avoiding spam is simply to guard e-mail addresses closely. For these people, an e-mail address is something to be revealed only to selected, trusted parties. As extra protection, an e-mail address can be chosen to avoid easily guessed names and dictionary words, and addresses can be disguised when posting to public areas. We have all seen e-mail addresses cutely encoded in forms like "
" or "echo firstname.lastname@example.org | tr A-Za-z N-ZA-Mn-za-m".
In addition to hiding addresses, an enigmatic e-mailer often uses one or more of the free e-mail services for "throwaway" addresses. If you need to transact e-mail with a semi-trusted party, a short-term address can be used for a few days, and then abandoned along with any spam it might thereafter accumulate. The real "confidantes only" address is kept protected.
In my easy survey of discussions of spam on Web-boards, mailing lists, the Usenet, and so on, I've found that a category of e-mail users gains enough protection from these basic precautions.
For me, however -- and for many other people -- these approaches are simply not possible. I have a publicly available e-mail address, and have good reasons why it needs to remain so. I do use a variety of addresses within the domain I control to detect the source of spam leaks; but the unfortunate truth is that most spammers get my e-mail address the same way my legal correspondents do: from the listing at the top of articles like this, and other public disclosures of my address.
