Meanwhile, the tools Google has for you to manage your mail reputation with Google are dreadful.

I'm so confused about how/why this thread focuses specifically on Google 
Groups spams. Some weeks ago, I calculated the percentage of spams vs 
legit-emails sent to my real-human-being users (a few thousand of them) 
for whom I host email (so, no spamtraps!), over a few-days period of 
time, and the amount of spam sent from Google servers was a full 1/3rd 
of everything sent to these users from Google servers.

That's horrific. (this includes emails sent from both their gmail system 
and their google workspaces business email system)

Also, the following is anecdotal, but as I was auditing a random 
sampling of those Google-server-sent spams at that time, I don't recall 
seeing even a single Google Groups spam, so at the least, that was a low 
percentage of all such spams.
