[Mailman-Users] is private mail being redirected here?

[Tom Neff]

I am seeing what appears to be a series of one-sided "answer posts" from

  <listadmin at aerosmithfanclub.com>

quoting messages that have not previously appeared on the mailman-users 
list.  If this person is redirecting private responses to the list without 
the correspondent's permission, that's considered rude Net behavior and 
they should cease.  If there is some other technical explanation, perhaps 
it's a Mailman issue.
