Other tips... Open your email in text only format first (no images) or filter with MailWasher. Spammers are know including a gif or jpeg image. If their server gets a hit fom this image then they know your email is valid and then sale it on a list of known valid addresses to other spammers.

As mentioned before, never buy anything from a spam email. Never reply to a spam email. If a service requires you to enter a email address to sign up, use a free email addy such as Yahoo or Hotmail. If a spam email has an unsubscribe button, do not use it, another trick.
