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!
