as spam.
Introduction of Filters
1 Basic Filtering Techniques
Early spam filters utilized straightforward rulesets that
filtered emails based on specific keywords, phrases, and
sender addresses.
2 Whitelist and Blacklist
The introduction of whitelists (approved senders) and
blacklists (blocked senders) became foundational in the
early spam detection processes, improving accuracy.
3 Limitations of Filters
Basic filters often lacked adaptability, leading to a high
incidence of false positives and negatives as spammers
evolved their strategies.
