Unpopular opinion time: this specific DNSBL single-handledly managed to convince me, a lowly email admin trying to be good, that DNSBLs are trying to make me do their work for them. They blacklist entire hosting companies subnets, despite the subnets hosting independently-administrated servers: I'm not the hosting company, so how can I request unlisting and answer "what steps were taken to fix the issue" in good faith ? They suggest using Mandrill as a reputable SMTP relay, and then manage to blacklist some of Mandrill's own outgoing IPs. So to be able to use emails I have to fight for the reputation of my server's IP (fair enough), fight my paid-for server's hosting company subnet reputation (so I guess I need to migrate my services from provider to provider everytime there has been mass infections by a spam worm in that specific corner of the internet), fight my paid-for email relay outgoing server reputation (so even the solution recommended by the very DNSBL is being blocked), and then spend unpaid time curating their list for them so it can be used by even more inbound filters and they can cause me more headaches the next time they fancy ? All the while my users cannot discuss with their customers and providers which rely on this list (without even realising it) ? Sure, they can count on it and drink water. -- Vincent Pelletier
