I haven't been following this discussion, but a few months ago I switched emails from one Google account to another Google account. I started a new group and invited everyone from my former group to join. (5000 members by groupings of 500) I would estimate that 95% of members who were NOT with Google came back as 'undeliverable'. My former group had no 'bouncers' as I removed them when they bounce, so the problem was not there.
Another problem I had was sending the invitations. If I sent 500 one day, I couldn't send more sometimes for over a week or more. I tried sending mail to the bouncers 10 at a time but most were undeliverable. I once had a group (HumorErotica) that topped 34000 members at one time, that I ran for over 15 years (Yahoo, then switching to Google when they began groups) but dropped it last fall because of continuous interference from Google. (Banning for no reason) They would unban after a few days or weeks. No explanation! I am now content with my little Nature Picture group (down from 5000 members to 1200) I no longer remove bouncers because there are some who receive mail (no problem) I haven't got the 'big picture' but I am convinced Google Groups is in a downward curve.
