No Spam Today! for Servers scans emails coming in from the Internet via SMTP or POP3, using a collectionof different filters like e.g. SpamAssassin™. This engine uses the following techniques to identify spam:The mail headers are scanned for some small inconsistencies that can give away forgeries: A mail date in the past or in the future, forged message IDs, and the like.The mail body is scanned for typical spam mail content, such as spam keywords, capitalized letters, or invitations to buy or click something.Queries to blacklist servers are used, e.g. to see if a mail has been submitted from a known open mail relay.Probability analysis of mails (Bayes filtering). Spam mails can be trained, so that similar mails are more likely to be identified as spam in the future.The result of all these tests is added up to form a spam score. A message is considered spam if the score exceeds a configurable treshold. You can modify the agressiveness of the spam checker by modifying this threshold: an agressive setting with a low threshold will find more spam mails, at a higher risk of legitimate mails falsely identified as spam (false positives).In the typical configuration, the subject of mail identified as spam is modified to flag it as spam mail, and a SpamAssassin™ report is added to the message. Now it is up to your mail server (or client) software to decide what to do. You can delete spam mails, or move spam mails to a spam folder, or leave the decision what to do with spam mails to your users.
