We have a one-way newsletter-type list. One thing we hate is that when we send out the newsletter, all the undeliverable messages get routed to the list maintainer even though the list is smart enough to determine it is a bounce and remove the bad e-mail address off the list. Is there anyway to have the list not forward the undeliverable messages?

On that same note, we can't seem to configure it so the recipient can just reply to the newsletter with the subject 'unsubscribe' because the list sees that it is a reply and just passes the message to the maintainer since they don't have permission to post to the list. What code do we need to delete from which file to allow the list to go ahead and try to process the message. Will it still process if if unsubscribe is the subject of the reply, but the original message is quoted in the body?
