I apparently stopped receiving messages on 2019-06-28. Looking at my
MTA logs, I was receiving messages just fine from addresses of the form
bounce+27952+43034+1459038+4027854@groups.io until at 20:55:37 GMT
there was a message from an invalid address which got rejected:

After rejecting that invalid mail, nothing else from the list was received.
