I don’t understand your rebuttal. Nothing actually counters anything I said other than you saying you disagree. The rest of the post isn’t contradictive. I agree spam is bad. I agree it’s important to stop it. My point is that spam servers can’t meet the requirements listed above. The only behavior that Gmail is calling out is the amount of emails being sent, but they’re still sending them. That’s not countering spam. That’s pushing people to use their own system which is identical but isn’t free.
