As you're finding out, Mailman and SuExec don't work too well together.
There is a FAQ at
which you may have seen.

That';s effectively what you need to do. You can use a different
user:group, but whatever user:group you use needs read/write access to
Mailman, so mailman:mailman is the easiest.

I think you misunderstand. Normally, mailmanctl must run as the
user:group configured for Mailman or as root in which case, it will
switch to Mailman's user:group anyway. Thus you are doing what needs
to be done.

The problem with access to private archives comes about if the web
server runs as Mailman's user:group, which is what you have to do with
SuExec because you can't SETGID. This in turn means that the web
server has permission to access private archives without going through
the private CGI. Thus, if it is possible to target Mailman's
archives/private directory directly via some URL, it is not possible
to block access.

That seems correct.

Two things control whether or not a list appears on the overview pages.
The list's own 'advertised' attribute, and if VIRTUAL_HOST_OVERVIEW is
Yes (the default), whether the host name in the list's hidden
web_page_url attribute matches the accessing host. See

There have been other reports of this and I've never seen a good answer.

The "You are not authorized to create new mailing lists" error occurs
only if the provided "List creator's (authentication) password:"
doesn't match either the site password or the list creator password.
Other validation tests on the list name, the owner and the list
password if any are applied before this, so presumably the form data
are getting to the create CGI, but the only explanation I can come up
with is that either the passwords aren't what you think they are (try
resetting them with bin/mmsitepass), the password isn't being
correctly transmitted by the web browse/web server, or the web server
isn't accessing the same mailman installation as the command line
utilities are accessing.

This list is the source of monthly password reminders and certain
bounce notifications that could otherwise cause bounce loops if a list
owner's address bounces. It is required in Mailman 2.1.x, but it is
going away in Mailman 2.2. Note that the password reminders are sent
separately per vhost and do come from mailman at vhost, but since there
is only one name space for list names (also going away in 2.2), all
the mailman at vhost lists are really the same list.
