Receiving bounces from announce list

This seems like a basic question, but I haven’t been able to find out the answer (at least one that seems to work).

How do I receive bounces that are generated by my Announce list?

In checking the status of my list, I see that most of my last several announcements have generated 1 bounce each, but I haven’t received any.

The Wiki doc says I need to set up an email alias called "", and that’s what I’ve done. My list is called “news”, and I have a forwarding-only email address with that name.

The Reply-To field is set to “Descriptive name <”, and people can reply to my announce lists, and they get forwarded to me, but I’ve never seen a bounce.

I do not have “catch-all” turned on.
