I'd like to create my own RBL that answers queries about IP, domain or

Data should be stored in a database (mysql, postgres, redis, etc) so

restart spamassassin (I think the simpler solution would be a list in
SA...)
How can I create this setup?
You need to build a Perl plugin for Spamassassin that connects to, and
queries the database together with at least one SA rule that triggers
the plugin via an eval:plugin_query() call where plugin_query() is a
plugin function that runs the database query using data extracted from
the message by SA and returns either 1 (the query found a match in the
database) or zero (no matches found).
that's way overthinking it.
SA already has perfectly good DNS query tools built in, why not use those.
It's pretty simple to set up your own local private DNS zones using rbldnsd.
Adding/updating those kinds of zones is simple as adding or editing lines in
a text file (as simple as echo ".this.bad.domain :127.0.0.2:" >> my-zone-file ).
No muss no fuss, not server restart, etc.
I run two private zones for this purpose, one a IP address RBL list and one a
URIBL list.
