Abstract
Detection of undesired electronic communication, such as spam emails, by comparing the email with a list of likely spam words and establishing the communication as undesired when the words in the list, are substantially present in the email, even if not completely present. For example, the match is close enough if the words have similar letters in similar orders, but with other letters separating them. Another aspect matches the words with a dictionary or rules defining spelling for the language. Emails with too high a percentage of garbage words are marked as undesirable.
