Here I share blacklists created from IP addresses I collect from my server logs (exclusively.) You can use them in your firewall.
They're updated hourly.
For who don't know it, this project generates IP addresses databases and sells the lists to big enterprises as Microsoft or Google to be used in anti SPAM software.
There is one of those lists in particular, the PBL that is especially annoying. It assumes any home machine is susceptible to be hacked and used by spammers. While this is mostly true there are "identifiable" exceptions. Mine is one example of those identifiable exceptions.
I run a web-mail server at home, that I administer myself. I have a few users with a few email addresses in use. This means I'm light years more able than gmail, hotmail or any big enterprise to monitor my log files and be sure no SPAM is sent from my machine.
At least rationally this should be the case of anyone paying 5 euros month extra to a ISP for an static IP and name reverse resolving as I do:
$ host roquesor.com roquesor.com has address 22.214.171.124 roquesor.com mail is handled by 10 server.roquesor.com. $ host 126.96.36.199 188.8.131.52.in-addr.arpa domain name pointer server.roquesor.com.
Spamhaus people know (it's obvious) there is quite more chances to receive SPAM from any big mail server (including Gmail.) And they're perfectly able to add checks in their database software to avoid including reverse resolving static IPs in their PBL list—what I meant by "identifiable." But, why would they bother themselves in doing that? On the contrary, big companies, do have interest in discouraging people from running their own mail servers at home, as well as sweeping small entrepreneurs away from the market, don't be surprised this is actually the service (not honestly fighting SPAM) big companies are paying Spamhaus (probably also spammers) for.
An interesting fact that supports my theory. Let Google, Microsoft or some ignorant lazy ISP admin tell the opposite, I've tried myself using not only the PBL, but all Spamhaus IP lists "exclusively" in my own firewall and, guess what, they didn't reduce the incoming volume of spam even a bit. If you have knowledge in the matter you can check this yourself and make your own conclusions.
