Actually, I think FAQ 4.29 may be the most relevant.

The first step is to make sure your VIRTUAL_HOSTS dictionary is
correct. It is built with add_virtualhost() calls in mm_cfg.py

The basic stuff that's needed in mm_cfg.py is if there are no changes
to DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST (i.e. the definitions in
Defaults.py are correct), then what you need in mm_cfg.py is

add_virtualhost(URL_FQDN, EMAIL_FQDN)

for each domain other than the defaults. If DEFAULT_URL_HOST and/or
DEFAULT_EMAIL_HOST are reassigned in mm_cfg.py then following those
assignments you need

VIRTUAL_HOSTS.clear()
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)

and

add_virtualhost(URL_FQDN, EMAIL_FQDN)

for each domain other than the defaults.

Other considerations are DEFAULT_URL_HOST and the various URL_FDQN must
all be distinct. if not, earlier add_virtualhost() entries will be
replaced by the last one with the same URL_FQDN key. Also, the
DEFAULT_EMAIL_HOST and the various EMAIL_FQDN should all be distinct
as well because there are several places where the dictionary gets
inverted and the EMAIL_FQDN is used to look up the URL_FQDN.

Given all that, the domain in the

List-Archive: <http://lists.DOMAIN-2.COM/pipermail/list-name>

header is looked up in the inverted dictionary using the list's
host_name attribute which in turn is the domain in the

List-Post: <mailto:list-name at DOMAIN-1.com>

Therefore, you must have either a VIRTUAL_HOSTS entry of the form

add_virtualhost('lists.DOMAIN-2.COM', 'DOMAIN-1.com')

or no VIRTUAL_HOSTS entry at all with EMAIL_FQDN = 'DOMAIN-1.com', and
DEFAULT_URL_HOST = 'lists.DOMAIN-2.COM'.
