That's the learning part, however there is also the distribution part :
is the email tagged ? How is the email transmitted by postfix to crm114,
and how is it transmitted to dovecot LDA ?
crm114 page does not even address those basic email settings, I did not
even see a command name on it, or a daemon or any thing...

What is the storage backend for the learned data ?
