Remailers are programs accessible on the Internet that route email and USENET postings anonymously (i.e., the recipient cannot determine who sent the email or posted the article). This way the sender can't be traced back by routing headers included in the e-mail. There are different classes of remailers, which allow anonymous exchange of email and anonymous posting to USENET and often many other useful features.
