I don't know about other servers, but on the systems I manage gmail itself is the #1 spam source since 3 years at the very least. If you look at my previous posts, I commented on this two days ago.

There's literally _Zero_ value in DNSBL/DKIM/SPF because of this. Email sent from reputable sources is actually _more_ likely to be spam than small mail servers.

Content-based filters are the only thing that work against this sort of spam.

Following your logic, his idea wouldn't work, and he doesn't make 115k a month. But, clearly, it does [if he isn't lying] - so I am not following.

I'm not contradicting his assertions. I actually confirm them: there is now a lot of spam coming from gmail. He's clearly one of the reasons.
