Task: mailman

You are setting up a local Mailman3 mailing list server for reading-group@local.edu with Postfix delivery inside the Terminal-Bench mailman container.

Mailman and Postfix are installed, but the list does not work until Mailman is configured at /etc/mailman3/mailman.cfg and Postfix routes the local.edu aliases into Mailman correctly.

Search terms seen in traces: mailman3 mailman.cfg postfix main.cf master.cf reading-group local.edu join leave aliases

Write the Mailman3 config, create the reading-group list with open subscription policy, wire Postfix transport and aliases to Mailman, and run the provided evaluator from /app.
