You didn't need to dedicate an IP address. All you needed was to
replace your

lists.pinyon.org CNAME quine.pinyon.org.


lists.pinyon.org MX 10 quine.pinyon.org.

There seems to be something missing here.

How did you re-install Mailman. apt-get? Source install? ???

In order to get a virtual-mailman, you first need an mm_cfg.py in the
place Mailman is looking for it. This is only /etc/mailman in Debian
and certain other packages, not a source install.

The list exists, but it's not in the lists.pinyon.org domain. This
'lists.pinyon.org', at least not in the mm_cfg.py that Mailman is
looking at. This could also explain why no virtual-mailman assuming
there is

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['lists.pinyon.org']

in mm_cfg.py.

Which of the following are you using. The changes in mm_cfg.py.works
look OK except the domains in
DEFAULT_URL_HOST   = 'lists.Pinyon.ORG'
should be all lower case.

And, I have no idea what lines 74-93 are.

Also, see the FAQ at <http://wiki.list.org/x/lYA9>.
