We had over 4K aol.com email addresses subscribed (to a couple lists) that appeared to be fake or at least always bouncing. Mailman is configurable to remove an address after a certain number of bounces. So it will retry an email address for a bit based upon what you configure it to do before it removes the email address.

So, that is why good email addresses may bounce and then if you have mailman configured to immediately unsubscribe, we had people get removed that should not have. As I said, we reverted this configuration change.

Thank you very much for the update and working on addressing those issues! 

For people who stopped receiving llvm-commits emails, unsubscribing & resubscribing might help to get back to receiving updates.

Cheers,
