Hi Andy, That has been happening to me as well. It started a several months ago, but I would split my list to 40 recipients and all would be fine. Then after a few days, no problem I can send out to my email group of 125 with no problem until it happens again. Recently, some messages are blocked and others aren't. Some group messages retry delivery over a period of time which results in multiple blocked replies for each recipient. At first I thought it was because of the graphics in my message, but even that is not consistently blocked.
I find if I send to small group of 2 or 3, it's fine. But that is too much of a hassle. Once I received a link that suggested I create a google group. But that is not what I want to do. My group emails are notifications and I want to keep it as such. And I don't want to subscribe to an email client. Yes, it appears the messages are blocked internally by google. Andy, I'm glad you've posted as I want to understand what is going on, too.
