Are you sure it isn't the other way around? When you have

add_virtualhost('lists.bijayant.com', 'dom1.com')
add_virtualhost('lists.bijayant.com', 'dom2.com')

The second entry effectively replaces the first because what they do is
add entries to a Python dictionary (a hash table). The first argument
is the key and the second is the value. So the first above makes an
entry with key 'lists.bijayant.com' and value 'dom1.com' and the
second replaces the value for key 'lists.bijayant.com' with 'dom2.com'

If you run Mailman's bin/genaliases after editing the list's host_name,
that should fix the virtual maps.
