[Mailman-Users] Outlook verification receipt via Mailman?

[Tim Tyler]

   Mailman experts,
  We are running Mailman 2.1.9 on a Centos server.  I recently had a 
request from a list owner that they would like to use the "Request a 
delivery receipt for this message" option in Outlook to all members 
in a particular list to verify that users have opened a 
message.  However, mailman seems to corrupt the delivery of this 
feature.  It works fine if she sends directly to users, but it fails 
if sent through mailman.   I know that other pop clients also have 
this feature and they also fail if using mailman.  Is it possible to 
configure Mailman to allow this feature through?   If so, how might I 
go about it?
