You missed

cron/mailpasswds
Mailman/MailList.py
Mailman/Cgi/create.py
bin/fix_url.py
bin/newlist

and also references to the VIRTUAL_HOSTS dictionary which always
contains at leasy the one add_virtualhost(DEFAULT_URL_HOST,
DEFAULT_EMAIL_HOST) entry in

Mailman/Utils.py
Mailman/Cgi/create.py
bin/fix_url.py
bin/newlist

Yes.

Yes.

See below.

Yes.

What do you mean by 'to which hostname the "aliases" file belongs?'. I
don't think the "aliases" file "belongs" to any host. Please clarify?

DEFAULT_EMAIL_HOST affects the value assigned to the list's host_name
attribute at list creation time depending on exactly how and with what
options the list is created.

The list's host_name in turn is used as the domain part of every list
email address exposed by Mailman. It also determines in a Postfix
integration environment whether virtual mappings for list addresses
are created in data/virtual-mailman depending on whether or not the
lists host_name matches an entry in POSTFIX_STYLE_VIRTUAL_DOMAINS.
