I have not yet enabled imapsieve -- so far I have had fairly good luck avoiding
spam simply by using SPF+DKIM+DMARC and enabling basic verification of incoming
mail with opendkim and opendmarc.
Lately I have been reading some books on "fuzzy logic" and "fuzzy sets" with
quite serious applications to artificial intelligence and neural networks that
might be useful to classify "ham versus spam" based on actual content and
context.
Spam versus ham is not the only sort of classification I would want to do on
large volumes of email -- I might want to have separate folders to
automatically classify incoming messages into separate categories for, say,
friends-and-family, legal-related email, specific business interests,
open-source-software or technical related email, mathematics, arts or crafts or
literature or hobbies, etc.
This kind of stuff must be easily configurable -- per user -- by individual end
users who are not experts in editing configuration files.
