- kjs3 5y agoOh sure...no argument there. But it's a scale issue. In this space, I have, say, 500M 'questionable' IP addresses who potentially send/receive mail (known bad, residential networks, uncategorized, etc.). So let's be wildly generous and say 0.1% of them want to host an SMTP server. Does the ISP commit resources to this tiny community, or do they commit those resources to keep Google/M$/Yahoo/etc happy, who constitute 9-something% of the business.
