Does anybody know about a decent piece of Open Source software to maintain a
#reputation database for
#email?
I want to keep track of everything my
#SMTP servers see, what
#SPF,
#DKIM,
#DMARC,
#SpamAssassin and the likes think of it all, and be able to process that into a database that those same SMTP servers can query to decide if they like a specific incoming connection.
The idea of having an external party get that much insight in my mail traffic doesn't really appeal to me.
