Most folks do this via NFS. They setup a primary mailserver then a
secondary that only kicks in if the heartbeat of the primary is
interrupted. The Mailman setup is stored in a home directory that is
mounted via NFS to both servers.
You could do the same thing via rsynch, though you should exempt certain
directories (like qfiles and data)

You can cut and paste the email addresses (one per line) into the web
admin tool and subscribe whole lists at one shot. You can also store
the email addresses (one per line, and *only* the email address) and
then use user_add to add the list of users to an existing mailing list.
