Ok, so I am getting it going, and my first attempt at sending mail to configure something with the password fails.
I look in majordomo.pl, and on line 477 I find that it is asking for the 'admin password' but the filename is hard coded as $clean_list.passwd (???).
The defaults were XXX.admin and XXX.pass (I thought). Still, shouldn't it get this from the listname.config file? And shouldn't it use XXX.admin instead (at least)?
Anyway, I changed the code to reflect the default name.
