Greetings!
I've recently deployed mailman3 for my community but have run into a
snag -- none of the emails that issue commands (eg.,
list1-<join>@domain.com, list2-<unsubscribe>@domain.com, etc. etc.) are
going through. They keep bouncing back with an undeliverable message.
I can create lists and interact with them otherwise just fine. When I
join from the web UI I can post and receive to that list. I've been
able to troubleshoot the rest so far on my own, but this has me stymied,
so any guidance would be greatly appreciated. Thanks in advance!

What is your MTA and how does it deliver to Mailman. What is the reason given for the bounces?
If your MTA is Postfix, what does postconf -n report?

This is the problem. Your domain is a virtual_mailbox_domain. You need to configure an alias_domain for your list domain and configure Postfix per https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.ht...

Thank you so much, Mark. That pointed me exactly where I needed to go. Everything's running nice and smooth.
Now, you wouldn't happen to know where to look for a halfway decent elist management primer, would you? I'm only half-joking -- I've never run something like this before, so am naturally a bit nervous.
Alight, you take care, and thanks again.

You're welcome. I'm glad you got it working.

There are links to Mailman 2.1 docs that might be helpful. Some settings names are different in Mailman 3, and the GUI is different, but the high level guidance is the same.
There is also https://docs.mailman3.org/en/latest/userguide.html, but that is for list members, not admins.
