Bug in Google Groups used as mailing-list:
1. Using email address A, email "subscribe" to email@example.com
2. receive confirmation-request reply to A
3. reply from A to confirm
4. get confirmation to A that I have joined
So far so good.
5. start receiving list email to an entirely different email address B! That is not proper mailing-list behaviour.
Specifically, B is my primary Google Account address, not the address that I subscribed to the list. Does Google consider this behavior a bug? Yes, you can configure it using a web interface afterwards, but the great thing about mailing lists is that you don't have to.
(What's a good alternative for hosting a small FOSS mailing-list? I checked a year ago and didn't find anything better than Google and self-hosted Mailman.)
