### 6.2.2 Main configuration settings

First, you need to add some macros to the top of your Exim config file. These just make the director (router) and transport below a bit cleaner. Obviously, you'll need to edit these based on how you configured and installed Mailman.

        # Home dir for your Mailman installation -- aka Mailman's prefix
        # directory.
        MAILMAN_HOME=/usr/local/mailman
        MAILMAN_WRAP=MAILMAN_HOME/mail/mailman

        # User and group for Mailman, should match your --with-mail-gid
        # switch to Mailman's configure script.
        MAILMAN_USER=mailman
        MAILMAN_GROUP=mailman
