Most mailers these days are not configured to do this. It makes it way to easy to quickly troll a domain for valid addresses for generating spam. I suspect this is how almost all mailers are going to work. It gets worse when mailing lists put themselves in a reply-to header. Then everyone on the list gets the bounce. There sure have been a lot of replies to a message with a sugject starting with "Do Not Reply To This Message..." Dave
