What good is that, if your IP and domain appear in anti-spam blocklists?
Problem solving is all about priorities! :)
If I was him I wouldn't worry much. The number of "real" MXen around the world using NOMOREFUNN or RATS-Dyna can probably be counted on one humans digits (fingers and toes). BRBL, on the other hand, gets mainstream use, mainly because it's active by default on Barracuda's appliances, and the installed base of such appliances is fairly substantial, in the US anyway.
But I would guess BRBL penetration is far less than 1% of MXen worldwide. If my own experience with the free access to BRBL is any indication--it times out far more often than it responds to queries--I'd guess few outside appliance owners are using it.
It rejected so little spam here compared to my local countermeasures and Spamhaus ZEN that I deconfigured it due to the timeout issue. If other OPs did the same for the same or other reasons, then penetration is limited to their appliances, with most of the installed base in small businesses and educational institutions in the U.S.. The OP is in Vietname, so again, he probably has little to worry about, being on these 3 dnsbls.
