As far as Mailman is concerned, the domain used in all email from a
list is the list's host_name attribute which is near the bottom of the
list's General Options web admin page. You can set the for a given
list from that page and/or set appropriate values for
DEFAULT_EMAIL_HOST and add_virtualhost directives in mm_cfg.py and run
fix_url to update existing lists. See the FAQ at

Note, if the list's host_name is what you want, but outgoing mail
references a different domain, it is probably due to your MTA
rewriting the domain. Fixing this is an MTA question, but see the FAQ
at <http://wiki.list.org/x/uYA9>.
