an application by that name. What is sa-learn?

sa-learn is part of spamassassin 2.50 and newer. If you've got 2.50 or newer, it should be on your system.


sa-learn allows you to train spamassassin's bayes engine to recognise spam and nonspam messages based on your typical email.

It works more-or-less like any other bayes analysis tool, it breaks the email up into substring tokens and then counts how many times those tokens appear in the spam and nonspam it has been trained with. These tokens and their hit rates are stored in a database. Later when mail comes in, spamassassin sees which tokens appear in the message and then computes a probability of spam based on the ratios of the tokens present. The bayes engine is treated as a group of rules by spamassassin, and the message gets spamassassin points based on how strongly the bayes engine thinks it is or is not spam.
