Solution

The correct option is B Heuristics scheme

Heuristics scheme Anti-Spam filtration technology is not an example of inbound protection schemes.

A heuristic method is an approach to finding a solution to a problem that originates from the ancient Greek word 'eurisko', meaning to 'find', 'search' or 'discover'. It is about using a practical method that doesn't necessarily need to be perfect.

Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples that employ heuristics include using a rule of thumb, an educated guess, an intuitive judgment, a guesstimate, stereotyping, profiling, or common sense.

Heuristic filtering refers to the use of various algorithms and resources to examine text or content in specific ways. The word heuristic describes a type of analysis that relies on experience or specific intuitive criteria, rather than simple technical metrics. The use of high-level algorithms allows for heuristic analysis of content, where humans can program computers to think in certain ways rather than just applying a purely quantitative analysis.

A spam filter is a program that is used to detect unsolicited and unwanted email and prevent those messages from getting to a user's inbox. ... More sophisticated programs, such as Bayesian filters or other heuristic filters, attempt to identify spam through suspicious word patterns or word frequency.
