Using the address show above as an example. I am finding that trying to "unsubscribe" from these new group addresses is impossible and as the addresses are all 'slightly' different you can't successfully block them. So my question is can you use special characters like we used to use when searching DOS commands to filter these out.
For example is there a way to ask to filter out *@*.firebaseapp.com This would be an attempt to filter out anything that has the .firebaseapp.com as part of the address.
