As you note below, the above entries are not what you want.


Is the '3wforum.com' domain what you refer to elsewhere as
'domain.com'. If so, the above is probably fine (although the cat is
now out of the bag). If not, then it probably should be.

Yes, this is a result of "VIRTUAL_HOST_OVERVIEW = Off" which in
addition to displaying all lists on the overview regardless of whether
the list's URL host matches the host in the URL accessing the page
also causes  DEFAULT_URL_HOST to be treated as the host.

I think it must have something to do with Apple's implementation of
Mailman. I suspect it has something to do with Apple's list creation
process. There is nothing in standard GNU Mailman that would edit
mm_cfg.py behind your back, nor would any non-Mailman process do this.

Perhaps others on this list who are familiar with Apple Server could
shed more light on this.
