Ah, I see. You want to protect the email addresses you're checking from a malicious DNS server that might harvest the addresses... OK. I'm not sure a DNSBL of email addresses would be effective. We see spammers mutating addresses all the time. I expect that's why there haven't been any widely-used email address DNSBLs. Regards, David.
