Thank you everybody for your really interesting answers. In this moment I'm just collecting informations.
I have one main problem: one of the engines used by our commercial antispam solution returns too many FPs. I'm gradually introducing spamassassin (included in zimbra) and I'd like to mitigate the FPs with some other checks... using a proven, well-known technology like AskDNS seems a quick and viable solution to me. Unfortunately a personal RBL may not cover all the use cases I'm thinking about and looking at the source code of a plugin that queries a sql or redis server can be interesting.
