We are trying to recieve email from a list serv that sends out messages with no return path. The error our linux firewall records is:

2006-02-10 10:55:41.034679500 new msg 785013

Linux  firewall forwards email too exchange 2003 on no other problems receiving email from outside. Looks like Exchange blocks email with no return path, how do we tell it not too?

Header on email message sent to gmail from same list server also indicates no return path but message is rcvd.
