Thanks, I was trying to copy a common configurations for ALL lists from 
the first one with /usr/lib/mailman/bin/config_list -o and -i, so I 
thought to include all the lists in accept_these_nonmembers

Now (listing all sibling lists EXCEPT "itself") I can achieve what I want.

I tried this in conjunction with sibling lists as defined in
regular_include_lists. Of course in this case I use the full list
name pseudoastro at poseidon.lambrate.inaf.it ...

Only I noticed that nesting of sibling lists is not allowed (it does not 
work as expected).

I created the following cases :

  list     members siblings         accept non members
  ----------------------------------------------------------------
  pseudoa  A       none             pseudot pseudop              *
  pseudot  B       none             pseudoa pseudop              *
  pseudos  none    pseudoa pseudot  pseudoa pseudot pseudop
  pseudop  A+x(,C) none             pseudoa pseudot              *
  pseudoi  none    pseudos pseudop  pseudoa pseudot pseudop

The three lists marked with * contain members (in the regime they will 
contain several members and they will be disjoinct, and there will be six 
such lists).

The other two lists (no *) are umbrella lists. They have no members but 
only sibling lists.

All the lists will be closed. Members of all real lists (and only they) 
can post to any of the lists.

However with the configuration given above, list "pseudoi", which is a 
2-level umbrella list (one of the sibling has siblings) does not work.
Message sent to it are never dispatched to pseudot.

The SOLUTION is to avoid nesting. "pseudoi" siblings are all three level-0 
lists pseudoa pseudot pseudop.

This way it works.

And it is also smart. Originally in pseudop I defined as member myself 
with a subaddress (A+x). This is not realistic but I did not want to annoy 
another colleague for the tests.

Mailman is so smart that when sending to pseudoi send just to A,B and C 
and removes the duplicate to A+x. Great !

While when receiving, a subaddress is honoured (so if I post from e.g.
lucio+fakenonmember, this triggers moderation). As it should be !

Maybe part of this information could go in a FAQ.
