How can we prevent Listserv from bouncing error messages to domains other 
than our own? We have a situation where internet "users" that are not list 
members are sending post messages to our lists and listserv is sending error 
messages back to what appears to be non-existant/bogus/spoofed Reply-To 
email addresses. What I am looking for is something similar to preventing Out-
of-Office replys to the internet.
