You are entirely correct: I should have been able to find that (after all, I was so close, and that was the readme I used when I set up the damn thing), and I just missed it on my skim. Explicitly filtering in: smtp_sasl_mechanism_filter = plain, login did the trick. I didn't need to filter out XOAUTH2. As always, thank you, Viktor.
