return receipts to a list

[ae6244 @ euler . math . USMA . EDU (Markert Erich Mr.)]

I operate several lists and have come across more than several
situations where someone has sent a message to one of my
lists with the return receipt option turned on.

What happens is when anyone reads this message using the same mail
package as what was used by the originator a return rcpt message
is sent back to the list.

My question is, is there anyway to filter these types of messages from 
getting back to the list?
