[MM3-users] Possible bug in Mailman 3.1 (Docker-mailman 0.1)

Mailman 3.1, docker-mailman 0.1

While I was trying to automate distribution of the files in /opt/mailman/core/var/data/postfix_domains I found what I think must be a bug.

Adding a new mail list (or deleting one) _does_ update the Postfix files /opt/mailman/core/var/data/ ,but adding a new mail domain does not. This is OK.

But deleting a mail domain that have lists associated to it

• does not issue a warning other than "Are you sure you want to permanently delete this domain?" which is not different from deleting mail domains without lists associated to it.
• the associated lists disappears both from the web interface Lists view and from the output of the "docker exec -it mailman-core mailman lists" command
• the files in /opt/mailman/core/var/data/ is not updated even the lists is being deleted.

1. Deleting a mail domain with associated lists should issue a warning that it has lists associated to it.
2. The files in /opt/mailman/core/var/data/ should be updated according to the deleted lists / domains.
3. Actually I think it should be impossible to accidentally delete a mail domain with lists associated to it.
