[Mailman-Users] Reply-to munging depending on sender subscriber status?

Is it possible to configure Mailman to set the Reply-To header of a  
message depending on whether the sender is subscribed to the mailing  


For an open mailing list set up to receive bug reports from users,  I  
would like to set

- Reply-To = sender, mailing-list  if the sender is not a subscriber
- Reply-To = mailing-list  if the sender is a subscriber

I've had a complaint from one of my collaborators that he couldn't  
filter messages correctly when they were sent directly to him rather  
than just to the list.  That's okay, and I like to keep most traffic  
on the list rather than hide it in order to publicly record the  
conversation.  At the same time, replying just to the list when I  
can't be sure that the sender will get my reply is not the right  
strategy, and since switching on the Reply-To setting, I've made that  
mistake many times.

Hence the desire to have the above option.

Thanks for your consideration.

PS.: The true problem happens on the client side, where replies that  
go to the list and the user aren't filtered correctly.  I would  
consider telling people to fix that rather than to set Reply-To if the  
above can't be done.
