Automated Bayesian Spam/Ham Training with Rspamd
At Onlime GmbH we have migrated the mail infrastructure in Dec 2019 from good old Spamassassin to Rspamd which greatly improved spam filtering. Rspamd offers a nice way of Bayesian learning in Rspamd statistical module. You can feed emails through
rspamc learn_spam or
rspamc learn_ham for manual spam/ham training to improve Bayes hit rate.
In the past, we have only internally used Bayesian training. Wouldn't it be nice to let all customers help us improve the Bayes filter / hit rate? Without even asking them to do so?
