I've just upload to sourceforge Patch tracker some code against CVS
which solves a related or similar problem.

https://sourceforge.net/tracker/index.php?func=detail&aid=457706&group_id=103&atid=300103

Provides functionality/behaviour similar to how
sendmail treats its aliases file.

eg
 alias1: alias2, alias3, alias4
 alias2: a, b
 alias3: b, c
 alias4: c, d

would only deliver one message to the union of alias2, alias3 and alias4 which
is a, b, c, d

We use it at the University Computer Club at UWA for a couple of our
lists.  For example, we have a technical discussion list which all
members can join but our systems administrators are automatically
included.

This is an example of the MemberAdaptor API in 2.1.  I haven't documented
it at all so it's really only for those comfortable with Mailman's
internals/python.

Yours
Mark
