Can you provide more information about this, or are you deducing a new policy from the sudden spate of bounces?

That's at least partly because it's bog-standard best-practice advice, and I see no evidence that anything in that document has changed recently. While it certainly could be a Google policy issue, this kind of thing is known to be caused sometimes by several other factors (eliminate any that just don't apply to you, of course): 1. One (usually more for Google) of your list posts actually was spam or otherwise abusive. 2. A group of your subscribers at Gmail took serious offense to something posted and reported to Gmail simultaneously. 3. One or more users on another list served by your host did something remarkably abusive and the whole domain was marked as a bad/incompetent actor. 4. A DNS-related snafu made it look like your whole IP block was transferred to a group full of abusers, even though nothing bad has happened in your own IP. 5. 4chan mischief. 6. Having mentioned 4chan, let's go right off the deep and mention "Cozy Bear" and the ilk. (That's a joke unless you're #natsec relevant, 4chan, unfortunately, while *very* unlikely is a possibility.) 1, 2, and 3 you can sometimes do something about, including getting in touch with Google, reporting that "this happened", and explaining why "it won't happen again" (in case 3, "not my list's fault"). Google is awfully big and may not care about you, but miracles do happen and 10 minutes writing an email to them might work one. YMMV, of course. > I certainly can't get any server anywhere to change their their > system configuration, Of course you can, for values of "you" == "all you users of the system." Remember, if you are having a problem due to a change in Google policy, most likely many others are as well. If you are a first reporter and do so in a measured tone, your credibility gets a boost. I don't deny that there are BOFHs and incompetent services out there, and all I can advise about them is "move" (which may not be a reasonable choice, YMMV). Obviously this route is unlikely to get fast action; I'm recommending it as an investment in the future. As usual, YMMV.
