How do I send usenet messages via e mail?

Many e-mail spammers go to great lengths to conceal the origin of their messages. They might do this by spoofing e-mail addresses (similar to Internet protocol spoofing). The spammer will modify the e-mail message so it looks like it is coming from another e-mail address. However, many spammers make it easy for recipients to identify their messages as spam by placing an ad phrase in the From field. Spammers try to circumvent the email filters by intentionally misspelling common spam filter trigger words. For example, "viagra" might become "vaigra", or other symbols may be inserted into the word as in "v/i/a/g./r/a". E-mail service providers have begun to use the misspellings themselves as a filtering test.
