1) Undo everything you did for mm-handler.

2) Be sure that the Defaults.py setting

MTA = 'Manual'

is not overridden in mm_cfg.py (You may have put MTA = None in
mm_cfg.py for mm-handler).

3) Run Mailman's bin/genaliases. This will give you a list of 10
aliases per list. Add these exact aliases to /etc/aliases.

4) Run Sendmail's /usr/bin/newaliases command.

That's it.

After that, each time a list is created or deleted, you will get a
notice of the aliases to be added or deleted in /etc/aliases. Make the
change and run newaliases again.

If you want to automate this process, see
but if list creation/deletion is rare, it may not be worth it.
