The reason you needed to run genaliases is that you created the list
before adding its domain to POSTFIX_STYLE_VIRTUAL_DOMAINS. Had you
added the domain to POSTFIX_STYLE_VIRTUAL_DOMAINS before creating the
list, you wouldn't have needed to run genaliases.

If your exim router were configured as this howto suggests, you could
have MTA = None in mm_cfg.py, and you wouldn't need virtual-mailman
(or POSTFIX_STYLE_VIRTUAL_DOMAINS), and new lists would just work.

Only because you are apparently doing things the Debian way instead of
the recommended way.

And you are configuring Exim so that you need to do all the Postfix
hassle which is unnecessary if you do it the recommended way.
>3. running genaliases is needed to update existing lists.
If you are relying on MTA = 'Postfix' and POSTFIX_STYLE_VIRTUAL_DOMAINS
and you create the list before updating POSTFIX_STYLE_VIRTUAL_DOMAINS,
this is correct.

add_virtualhost directives have nothing directly to do with
virtual-mailman. They provide a Python dictionary mapping from 'web
host' to 'email host'. This is used to determine the email domain for
a created list when creating it from the web or via newlist without
specifying an email host. Also see the FAQ at
