The answer to this question is that lists created by the web create
interface are created in the domain which is the host name of the url
of the current web create page.

Creating a list in an arbitrary domain can only be done by bin/newlist.
 bin/newlist --help
for more info, but note that based on the following, you don't want to
do this. See below.

This is not the way Mailman virtual domains work. See
for more info on what add_virtualhost does. Having multiple virtual
host entries with the same url host leads to unpredictable results.

As far as Mailman is concerned you appear to have only one virtual
domain which is the domain of the web interface which if I understand
correctly is the same for all lists. What is different is the e-mail
host for the lists. This can be changed after the list is created on
the list's General Options page using
  Host name this list prefers for email.
  (Details for host_name)

Defaults.py, you don't need any add_virtualhost() lines in mm_cfg.py.
If they are not both the same, then instead of the three
add_virtualhost() lines above, you probably want the following two

>POSTFIX_STYLE_VIRTUAL_DOMAINS = ['virt1.com','virt2.com']

This is probably OK if you are using Postfix. You don't say, but do you
also have

MTA = 'Postfix'

? Read the comments on these in Defaults.py

I hope this helps.
