2021-02-01 Thread Chris via mailop
As per the RFCs, DNSBLs should only be returning 127/8 values, anything else must be considered an error by the filter and ignored instead of being a listing. This is how you avoid DNSBLs blowing up on you when their domains accidentally expire and are wild-carding with fixed advertising IPs.

Caution brain bending ahead: Secondary MXes have a role as your main mail server. Long experience with spambotnets reveals that most of them are pretty stupid, because their MX capabilities are limited. In fact, many spambots infections don't do any DNS lookups at all, and rely on pre-record
