- Whitelist/Blacklist – This filter is simple, whitelist is a list of emails you always receive based on domain names of the full address, whereas Blacklist is a list of emails you never want to receive.
- Bayesian analysis – This is where the brain is, Bayesian filtering technique uses an artificial intelligence to learn which word or company to look out for spam content, the idea is to make a statistical analysis of the probability of each word or token ($%&), based on how often that word/token occurs in spam as opposed to legitimate mail (ham).
- Mail header analysis – Mail header checking consists of a set of rules that, if a mail header matches, triggers the mail server to return messages that have blank “From” field, that lists a lot of addresses in the “To” from the same source, that have too many digits in email addresses (a fairly popular method of generating false addresses).
- Keyword checking – This is another widely used solution where the content of the email is scanned to filter out specific keywords such as viagra, credit card and more, such as: $$$ or s c a t t e r e d text. or V-i-a-g-r-a
