I am running Mailman 2.1.5. I have several lists where one is allstudents,
and several others that are a subset such as commuters, residents, etc.
Sometimes messages are sent to the allstudents list which should have been
sent to one of the other lists. How do I redirect the message to the subset
list without it going to the allstudents list? Can this be done through the
admin interface? If not then how?
