[Mailman-Users] Sibling lists (and other lists as list-members)

[Adam McGreggor]

This is almost certainly down to my ineptitude, with this "new"
feature, but I'm wondering if any of you folks can help.

I've got three (relevant) lists, all on the same machine/domain,
(Mailman 2.1.11; Python 2.5.2): 

    nowhere-crew 
    nowhere-leads 
    norg.bored

nowhere-crew(@lists.goingnowhere.org) has
    <nowhere-leads at lists.goingnowhere.org> 
and
    <norg.bored at lists.goingnowhere.org> 

as non-digest list-members (along with its own 'ordinary' (well, as
ordinary as euroburners get) list-members): I want both of those two
lists(members) to receive mails sent to nowhere-crew (that bit works).

What I don't want is for copies of the mail sent to nowhere-crew
to be sent (twice/thrice) where an email address is on either/both of
the other two lists.

It seems to me that putting:
    nowhere-leads at lists.goingnowhere.org
    norg.bored at lists.goingnowhere.org
in 
    regular_exclude_lists 

should work. That's my understanding of things from past-list posts,
and the little note on the wiki.

Except it's not quite working. I'm still getting the message twice
(thrice), when sent.

I'm a wee bit out of ideas, and can't work out what I've done wrong.

Nothing odd in the (abbreviated) headers, that I wouldn't have
expected, either:
    
(I've foo.example.org'd the Message-ID, but they are consistent)

I imagine I've made a very simple mistake, somewhere. Could someone
with more clue in this area (Sibling lists) help me out.

Thanks, as ever,
