I too, am looking for something like this! I have spent the last four days "fixing" my email after I introduced dspam into the equation.
I currently creating an Ansible playbook with: Postfix, Vimbadmin, Roundcube, Dovecot, Dspam, Sieve, Dkim, SSL, Memcached, Nginx, PHP-FPM. With postfix and dspam using mysql.
If things are stable I'll put this playbook on github.
I'm currently playing with dspam.
