[Mailman-Users] Duplicate Messages

[David Andrews]

I have a problem, and don't know if there is an easy or viable 
solution.  I run a bunch of lists for an organization, over 150 
lists, about 80 percent public and 20 percent private.  Periodically 
there are messages that need to go to everyone, or almost 
everyone.  However, people belong to multiple lists so many people 
get duplicate copies of the same message.

Is there any way to send to everyone, or sub-sets of everyone?  Is it 
possible to subscribe everybody to an announce-only list, at the same 
time they subscribe to their chosen list or lists?  Not sure I want 
that approach, but an option if possible.
