We are planning to set up a Discourse-based alternative mailing list archive (primarily for wikitech-l), and want to understand better the intricacies and limitations of how Discourse converts emails to a mailing list into posts. We'd like to set up a test list (firstname.lastname@example.org) so we are able to experiment with that. The list should have the same settings as wikitech-l. It can be deleted once testing is done (a few months, I'd guess). List admins: email@example.com, firstname.lastname@example.org.
If you can suggest an existing test list, that would be fine as well.
