Example of how the blacklists contain essentially no information: every one of Gmail's outbound VIPs is in a SORBS blacklist. Every one I checked is in at least 20 other blacklists. So if you just don't want to get mail from hundreds of millions of people, subscribe to IP blacklists.
That's not true, unless "VIP" means something that I don't understand.
I use SORBS on a rather busy mail server with thousands of messages sent to and from Gmail daily. Aside from very occasional SORBS rejections, which happen more often with Outlook.com and Yahoo, this simply isn't the case.
Post a Gmail outbound VIP that is not in a SORBS blacklist, then, if you're so sure.
Whatever the opposite of a disclaimer is: I was the tech lead of gmail delivery SRE for four years, so it's likely that I know more about this topic than anyone on this board.
