DNSBL checkers list
Since I am now running my own smtp-server, I have to deal with different black list servers myself and check my IP from time to time if it’s there or not.To cover pretty much everything valuable:
My IP was in 2 lists, DAN ME, APEWS and Barracuda.
DAN ME is a list maintained by some loser, who lists there all TOR-related IP addresses he can find. Unfortunately he lists not only the exit-points, but relays as well. Fortunately, his list is automated, but I had to shut down the TOR node.
Barraccuda removes by request, however, sells “subscription” for $20, so you will not be in the list again. That’s low!
At the moment it’s in the APEWS for 3(!) years and the owner has a long faq where he is explaining why he would not remove you ever.
Thinking of extra VPS for the additional MX.
